Brown sound is kinda light tan

[Dante]

I'm looking everywhere, I can't find it

Can you see it in this pic?

[MarshallJMP]

You need some new glasses 

Seems you also have an early version, nr 74 (sr 60074) mine is nr 10 (sr 60010)

How did i miss that?  :facepalm:

Now I know that IC means 'big black thingy with lots of posts...looks like a chip'

[Dante]

Just ordered for $6.50 + free shipping

Let's hope it solves your problem.

I got the part in the mail yesterday, just found it as I was leaving the house this morning....I'll try it tonight

[Dante]

Whelp, that was the easiest thing in there to change....but it didn't make any difference.

My problems: No effects loop, No distortion (all patches sound flat/clean) even with DIST voicing. Something's up

[MarshallJMP]

Do the controls react? like od1,2 master volume, chorus? BTW I mean can you hear a difference

[Dante]

Nope, all patches sound dry, regardless of OD1, OD2, voicing etc.

[MarshallJMP]

Do you have a multimeter?

[vansinn]

Hehe, he does, said so in #25 ;)
Weird problem, wish I had something to offer..

[Dante]

Okay - check this out....

I disconnected the FX device, no LOOP. Just plugged into the Classic and ran that straight into the power amp. PATCHES ALL WORK. They still sound muffled - like the tone is being choked out of them. I turned off the noise gate and it stayed the same...choked out...Brown sound is kinda tan, Brutal Distortion sound is kinda 'Classic Rock' overdrive or fuzz. Weird

So, I reconnect the Boss GX-700 cables via 4cm, and my preamp is dry / clean every patch. I don't get it. Must be an issue with the GX-700, I'll swap it with my spare to see whassup.

Still...the Classic's tone issues persist :/

ps. Yes, I have a multimeter

[vansinn]

Doesn't sound like an issue with the GX, but rather something reacting incorrectly within the Classic.
You should actually be able to do the 4cm cabling without any device, just the cables going out/in, which should reproduce the same behavior.

But hey, you got a Classic with fully classic sounds, howzat for a win-win.. :facepalm:

[MarshallJMP]

Does the SS clean sounds also muffled?

[Dante]

I believe the SS sounds normal. The Classic seems to be working without anything plugged into the FX loop. I'm running in FX loop A, and it seems FX loop B has it's own issues :/ It squeals mightily

This unit is a mess, I may be dragging my old one out of storage to try it out....or, better yet, I'll ship them both to Europe to be fixed correctly (hint hint)
