One or more of the fets on the FX PCB probably.Cr4nK wrote:Hi everyone,
I actually have this problem. When I got my guitar str8 in with effect loop disengaged everything work good, but then when I enable it there is a big drop in volume (nothing plugged into effect loop). I got to turn the master all the way to 10 to hear any playing.
What do I have to replace to fix this problem?

Indeed. At work we have to use static dissipative jackets, dual heel straps, and static protective gloves. The workbenches have to be outfitted with extensive grounding mats and wiring. You have to keep all paper away from these parts, as paper can hold a static charge. You can't even use regular cellophane tape near a static controlled workstation, pulling a 8" length of tape off the roll can generate thousands of volts. Even our tools have to be static controlled. It's complicated and expensive.SteveD wrote:If only it were that simple.DeanM wrote:... touch a radiator or something first before handling!
well theres not a whole lot else the average diy'er can do at home!SteveD wrote:If only it were that simple.DeanM wrote:... touch a radiator or something first before handling!
I'm doin a student co-op workplacement for college at the moment with EMC in cork, ireland. its exactly the same in there too! theres jackets, mats, ankle straps, esd boots, even the FLOOR is esd compliant! theres test stations at regular intervals that you stand on to test your gear is doing its job etc. and everyone working there has to do an ESD course EVERY year. its pretty strict.MKB wrote:Indeed.

The trick with ESD protection is not to get everything grounded, but to get and keep all pins and the installer and tools at the same voltage level.
