Line 6 Spider IV 150 - Modeling 150W 2x12" Guitar Combo Amp Reviews

4.5 stars based on 9 customer reviews

    This amp was basically a replacement for a Flextone that I foolishly sold a few years ago. I don't miss the Flextone now, this amp sounds great at any volume and nothing is lost when it is pushed to the max. A foot controller is definitely necessary.... great value!

    Fantastic Flexibility

    This is the first non-tube amp I have ever purchased. After taking a nearly 15 year hiatus from playing guitar, I have been rebuilding my guitar and accessory inventory and getting back in the saddle. I did not want to drop the money on a big tube amp but I wanted something with flexibility and I think I have found the holy grail! This amp does a great job of reproducing a wide variety of tone styles from amps of past and present day. I have never had that type of flexibility in anything else I have owned. One of the most fantastic features of this amp other than the built in effects and 16 different amp models is the 64 banks of user-defined presets. No more tweaking dials over and over to dial in a particular sound. Just get it once and save it to a memory bank and call it back up whenever you want! That part becomes even easier with one of the Line 6 FBV MkII foot switches, which I'll have to get soon! I couldn't be happier!

    Great Amp ! Plenty of Power !

    I got this Amp for some of the "bigger" venues that I play. And it does'nt disappoint ! As with all of the new Line6 amps, its just a matter of finding what works for you. And buy the way IT CRANKS ! The speakers are clear and full sounding. Great amp for the money for sure.

    Monster Amp For the money !

    After a good freind of mine suggested I try a "Line6" amp (Knowing I am a digital fan) I acually bought two. I got this one for some of the larger venues we play. Now I got the "Short board" controller also. (If your going to gig with these amps, its a necessity) The effects are clean and easy to set up and customize. The stereo effects are awesome ! The Celestion speakers they use in these amps sound full and clear. And buy the way it CRANKS ! Its built solid, and well worth the money. If your looking for an amp to play larger venues, this is the tool for the job. Its a Monster !

    A Solid Product That Will Engage Your Music for Years

    I have been playing a little over a year and most of that time was spent playing an acoustic guitar. This summer, I switched over and bought a Taylor Solid Body Standard. I made several purchases as it was hard to find the right equipment. Tone being good only in the ears of the beholder. I purchased a Peavey Vypyr 30W, and then a Roland Cube 40 XL only to be unimpressed by the amps as I felt the quality tone produced by my Taylor was being limited. Well after I purchased the Line 6, I was happily surprised to find the wide world of my Taylors tone producing capability to be matched by Line 6's amps ability. Hands down, I am pleased that at this price point, the Line 6 product is the beast. I also have to say that BOSS GT-10 modeling and Peavey's modeling abilities and user interface as so far behind Line 6, that I do not understand why any computer savvy user would bother with either BOSS or Peavey.

    Great Value

    The Line 6 Spider IV 150 has to be one of the best values in guitar amplifiers today and could be a 5 star amp if it holds up. The amp is powerful and produces high volume clean sounds with its 2 12 inch Celestion custom speakers. I do not have detailed specs on the speakers so I do have some concern about their longevity given the relatively low total price of the amp. The volume is more than enough to set your ears on overdrive and to compete with the loudest of drummers with power in reserve. Any desired distortion really comes from the multitude of FX selections and not by overdriving the amp. To many purists who think that overdriving tube amps is the only proper way to get the sound they want may be disappointed in this solid state amp, but I believe even those purists will find the ability of this amp to come close to producing the sound they desire by choosing one of the many, many built-in FX and tweaking it if necessary by editing capabilities contained within the amp. I will not go into the hundreds of sound presets because they are enumerated within the sales literature here on the Sweetwater site or on the Line 6 website which contains many samples for you to hear. I conservatively will just say there are many, many sounds and they are mostly very, very good. I would also like to point out the efficiency by which sounds are chosen and edited with the rather limited number of knobs, switches and cursor controls on the face of the amp. The relatively few controls may deceptively lead one to think that the simplification means reduced variety and flexibility. This is far from correct considering the vast flexibility of sounds that this amp can produce. These controls are easy to use with very little learning curve regarding the use of the systems and menus. One professional caution: The number of presets may lead to false satisfaction and reduce the amount of your editing and experimenting because you may easily be overcome with the number of presets available. When you find a preset that is close, you will be tempted to accept it. Please take it a step or two further beyond mere acceptability by editing it to make it your perfect sound. It is just too easy to accept what the amp gives you instead of you telling the amp what it needs to give you.

    In my opinion, these presets or your personally edited versions of them will permit the disconnection of many of the floor boxes and pedals which many guitartists use today. The problem here is that foot controls are absent from the Spider IVs unless you spend extra money on one of the elaborate foot boards that Line 6 sells to go with the amp. When I bought my Spider IV 150, I also needed to buy a Line 6 footboard to go with it to take full advantage of its amazing capabilities. (I previously had been using a Korg Toneworks AX1500G and a little Korg Pandora PX5D. These are/were fine multifunction units but were add-ons and not integrated with the Line 6 amps.) In my case I chose the FBV MkII "Shortboard". It has 13 lighted switches, an expression pedal and a lighted display panel. There is a more elaborate board with 2 pedals and more switches. This board seemed a bit too much for me, but it would certainly be at home with a "Spider" amp because you would need eight legs to operate it. There is also an express board with 4 switches and a pedal which seemed insufficient for the Spider IV 150 amps functions. Generally, the shortboard addition increases the discounted price of the amp by 40%, but I believe this board is necessary for the amp to be a complete piece of equipment. The shortboard is also the vehicle by which updated software and additional sounds and FX may be downloaded from the Line 6 website into the amp. The shortboard itself is built of high quality, heavy duty materials which seem like they will last longer than you. The steel footswitches feel great and do not have the spring loaded clicker that makes a noise each time you step on the switch. The display is bright and large enough to easily read while standing. I am no expert in foot controllers, but this one says quality as soon as you remove it from the box. While not being excited about spending the additional money for the board, it is still probably a lot less than the large investment in various foot controllers that may be necessary for some guitarists. But, it integrates so well with the amp, it is difficult to refuse to add it. Accordingly, I think it is most beneficial to include something about the boards in any review of the amp. If you already have a large investment in FX foot controls, you do not have to have the Line 6 board, but I would try to remember to consider it as a possibility if you are in the market for one or two additional FX foot controls later on.

    Is the Spider IV 150 still a great value after spending the additional money for the "shortboard"? I still have to say absolutely, because the value added by the shortboard is significant and it makes a great amp become a great package. While I highly recommend the Spider IV 150, that is a personal opinion and obviously, you should only make a purchase decision after trying one out. I think most will be pleasantly surprised. While I think this amp is a great value, if it is on the high side of your budget, I think the several less powerful versions might make a great deal as well.

    Great Amp At an Affordable Price!

    I have spent thousands of dollars over the many years I have been a musician. This by far was the easiest and most cost effective decision I had to make! A Great Amp at a perfect and affordable price.

    Fun for a little bit

    I bought this used from a guy listing on craigslist. When I tried it out, I really liked it. I played with all the effects and they never seemed to get old. It's been a year since that, and it's no longer that fun. The high-gain channels have lots of feedback, and even with the built in noise gate they're noisy. The cleaner channels are decent, however the Twang ones aren't nearly what they should be. I tried it with a Telecaster and it wasn't as twangy as I'd like it to be. The Tremolo effect doesn't have enough customization to my preferences either, as you couldn't get it to a slow rate while still a killswitch-style sound. Sometimes when I was playing the amp would just turn off and turn on, which makes it cut out for about 3 seconds. Also, sometimes when you turn it on, with the FBV Express MkII, the expression pedal on it wouldn't work until you switched channels. The tuner was pretty good though, the only problem is it only tuned in flats, which was confusing when I didn't know my musical alphabet very well. The volume on it is very sensitive at the lower settings. When at 1-2, no sound is emitted. Any higher and you get a little bit of sound. Just a bit higher and the sound just blasts you in the face. The positive things I could find about this are its speakers (Celestion Vintage 30), it's fairly lightweight for a 2x12" (about 55 pounds), its ability to store presets and keep them on a computer, and the looper, although it only looped 8 seconds. The Clean channel was pretty good too.
