Line-6 DL4 “External Master-Volume” mod

Great FX pedal, but a few issues with switches and lack of overall volume controlability …

some basic mods:

remove R36 and R37 from board (hold part with tweezers and alternately heat both ends until free) … run wire pairs to pads of said resistors

replace switches with quality soft-switches and insert dual-100k pot at end of battery compartment // Heavy Duty Momentary Foot-Switches

Smallbear Reverse Audio taper 100k

In the end you got yourself an improved version of an already great design … except, now there’s a Master Volume control in your signal path … useful in some rigs (read the manual for the direct bypass options)
