1) Replace all the input/output buffer components with high quality parts for clarity of signal. Remove the electrolytic caps (C4 and C8), replace with
Nichicon and WIMA; Remove TL072 op-amps (U3 and U22) and replace with Burr Brown hi-fi OPA2134UA.
2) Removing RF filter caps from pre-relay inputs and post-relay outputs (C1,
C36, C23, C24) in order to make the pedal TRULY true bypass and eliminate tone sucking.
3) Reduce R36 and R37 from 36k to roughly 22k (24k according to Jeorge Tripps) for increased gain of output buffers. This will fix the "volume-drop" problem some people experience.
#2 and #3 are crucial to do. #1 is just for tone snobs. Furthermore, #2 was caught pretty early in the revision history so pedals built after 2001 already have this implemented. |
