Step on it and Wail!

Music Background: live playaa! not a bedroom wanker....
This is by far one of the best boost pedal I've ever own without spending over $50,without killing your tone, and it also beat out those high $ pedals as well. The secret lies in how to set it up. L... read more [+]evel Knob at max,Tone knob at 10'Oclock and Drive knob at 9'Oclok which I use as the level knob. This goes in front of My awesome Boss OD-3 which I use alot for rhythm work. And when solo spots come up during live gigs I step on the SD-1 and go at it baby! I need to buy another one of these and another Boss OD-3 for my smaller set up I'm building soon..... close [-]

Beats the Tubescreamer

Fantastic gritty overdrive tones, beats the tubescreamer hands down. Almost the same circuit as the tubescreamer though - very moddable. At $50 there's no reason why every pedalboard shouldn't have on... read more [+]e of these. Only complaint is the distortion bleed-through, but I don't use it on settings that high and like I said, very moddable. close [-]

GREAT FOR LEADS BEHIND A FUZZ OR DISTORTION PEDAL

by J.C. AmericanDeluxeStrat from Tazewell,TN

Music Background: 21 Year Musician
I added the SD-1 to my pedal board right behind a BOSS BD-2 "Bluesdriver" the BD-2 creates a perfect crunch , then when the SO-1 is engaged it creates a perfect lead tone on my marshall tube amp. Alon... read more [+]e the tone is not so great , but behind a good distortion or fuzz pedal this thing sounds amazing. Sounds best coming through a tube amp, looses a little of its bite coming through solid state. Bump it in on a tube amp with a little fuzz and you'll love the tone. close [-]

Boss SD-1 Super Overdrive

by L. Clepper from Sweetwater, Tx.

Music Background: Hobbyist
I use this pedal in front of my amps own distortion as a lead boost. It works great for a volume boost without changing the sound of your amp. Great for fast ripping solos especially with a wah pedal.... read more [+] Noisy when cranked all the way up (all knobs), but just roll back off the drive a bit and your good to go. My settings are as follows:
Level: 50%
Tone:70%
Drive: 90%
Good for bluesy stuff too, with a little reverb in front of clean channel. I cant seem to find a reason not to own this thing, especially for the price. Its not designed for Death Metal. Sounds fatter than the Tube Screamer, IMHO. close [-]

Boss SD-1 Super Overdrive

by Rick Rice from Buffalo, NY

For 40 bucks, the Boss SD-1 is the best Overdrive value on the market!

The circuit is very similar to that of a vintage Tube Screamer, except for the addition an additional diode in the cli... read more [+]pping section. The resulting asymmetrical wave pattern produced a deeper, richer bass response than the Tube Screamer’s symmetrical clipping section. The SD-1’s sound is also less focused in the midrange frequencies than the Tube Screamer. There is a negative to this pedal...with some guitar and amp combinations, when you max out the SD-1’s Drive and Level controls, you can hear some distortion filtering into your clean sound even when the SD-1 is turned off. This phenomenon is inconsistent; i.e., I have heard it at times…other times I have not! To remedy the problem, back off a bit on both the Drive and Level controls or perform a simple circuit modification improves the bypass circuit and eliminates the bleed-through. close [-]
