Excellent Amp!

Have been playing real tube Marshalls since the 90s. Bought this from Sweetwater just before Christmas so have had it for about a month. Saved the box to return because it was so expensive in case I did not LOVE it. Was looking for a hand wired boutique amp for home and some gigs. This is expensive for Marshall but relatively inexpensive for a boutique amp (and it was hand made by the company with probably more amp experience than any other). Materials and finish are top quality. Range of sound is fabulous. KT66s deliver shimmery cleans that are punchy when you have more pick attack. The Gain and Master Volume deliver that amazing Marshall OD sound at volumes that are tolerable for gigs or at home without attenuator. Built in effects loop is seamless with boost pedal - reverb and other effects does not change one bit. I usually set the gain at 50% to 75% and roll back the volume on the guitar to get nice warm cleans. The boost is really like a second channel and a simple execution of what you need to switch from rhythm to lead. The 30W to 5W switch works as expected making the breakup happen sooner. Paired this with 2x12 cabinet for nice full sound. With a five year warranty, attention to detail, Marshall reliability and all of their expertise building classic tube amps, how could you go wrong. It sounds just like excellent Sweetwater review. Highly recommended.

Best amp Marshall has made in years

I have been using Marshall amps since the 70s and have owned almost all of them at one point. I still have my wall of Marshall's at home but I record with my Kemper so they are all more for fun. Marshall did not do a good job rolling this amp out, also the styling is subjective (Sourmash is bullding me a classic 100watt box in black). Having said all that please do not any of that make you overlook this amp. If you love single channel amps and controlling your tones with your guitars volume you have to consider this amp. After a good week playing it I can say with confidence that not since some early JMPs has there been a Marshall that sounds as good as the Astoria Custom does, I do not say this lightly. It's that good. I have it paired right now with a 4x12 of Celestion G12H-30s and love it. The amp has power reduction taking it from 30 watts (really about 22) to 5 watts. The way it works and the way it sounds is better by far then then any other power reduction I have used in an amp. This includes Marshall's EPA system. The amp remains very punchy and articulate at 5 watts of power. The footswitch controls the loop and a built in boost, you can set the loop as a volume reduction or boost if you want. There is no need for any OD pedal with this amp, I never use more then 5 on the gain and it is more then enough even without the boost engaged. There is a "Body" control also in this which is great for those single coil guitars to really thicken up your solos. I cannot imagine any professional player with cork sniffing taste not falling in love with this amp once they play it. It really is one of the top 5 Marshall's ever IMO. I usually use two types of tones with my playing, one is a classic rock tone similar to the Scorpions or Dokken and the other is a blues tone in the style of Robin Trower. With a Supernatural Reverb and a TC Vibe this amp nails early Trower. I would say it is not suitable for metal but not a problem with hard rock. Out of the box with a Les Paul it is very vintage AC/DC with very little tweaking. The open chords ring out every note unlike most amps when using a good bit of gain. No mud here. I also want to comment on the build quality. As someone who has had some of the world best builders make me handwired amps over the years Marshall does an amazing job wiring this amp, very high quality which is reflective in the price. For the gigging musician this head is about as close to perfect as there is. 30 watts is surprisingly loud and even 5 watts would work well for small venues. Quality, tone, and flexibility make this a amp I think I am going to get a lot of mileage out of. If you dig the high end Marshall amps over the years give Astoria a go, I am absolutely loving this amp.
