DOD FX55-B Supra Distortion
Why not repeat the same perfect scheme that worked pretty well ten years earlier?
DOD FX55 Distortion
This one apparently has the same circuit board as the FX50. Original used TL062, so TL061 is probably the right chip for the job. Like FX50, the other half of the opamp didn’t touch the signal path when engaged at all, so i decided to go with a single.
DOD FX50-B Overdrive Plus
Here’s DOD’s step up from FX50 🙂 Just finished building this. The pot tapers are not mentioned in the schematic, so i went with the usual tapers from most designs. However. Volume needs to be linear and drive reverse log to get the circuit act like the original unit. Other thing was the 470R resistor … Read more
DOD FX50 Overdrive Preamp
Here’s DOD’s step up from OD250 – from around ’82. On the original unit, the chip used is TL022, which is low power dual opamp – But the other half doesn’t touch the effect side at all – It’s only used as a buffer for the bypassed signal. So i made the layout to house … Read more
One Knob Big Muff
Request. This is a One Knob Big Muff based on Joe Gagan’s schematic and values. It makes sense in a lot of ways because many people dime the gain controls anyway, but you may want to experiment with the 39K and 47n from Q3 collector to Q4 base to get the tone setting the way … Read more
Fulltone RTO Robin Trower Overdrive
Info about the original: Robin Trower is known for TONE. While working with Robin during his 2008 tour, I developed an overdrive truly worthy of the Trower namesake. Touch responsive, huge sounding, sustain for days… and crystal clear when the guitar’s volume knob is reduced for great live dynamics. Being that Robin uses Fenders as … Read more
