Posted on September 16, 2014August 9, 2019 by abram

Here’s another in a line now of DOD pedal mods. For this FX55B, I decided to go for more of a BigMuff sound. Playing around with this pedal initially, I found it to be like most mass-produced distortion/fuzz effects. It had a very thin sound and that notorious volume drop that you may have heard…

Boss Tremolo TR-2 w/ C4 Mod +Gain Boost
