Pittbull Classic Boost Switch Issue

Amps & Cabs Pittbull 100/CL
1

I recently picked up a Pittbull Classic (Model G-100-CL, Serial CLD940202) that has some issues with the boost switches on both the clean and dirty channel. The boost is not enabled when either the switch is pushed in or out, however the boost is temporarily enabled when the switch is partially pushed in.

I’ve been trying to make sense of what’s going from the top of the board but it’s obviously challenging with no schematic. My wild guess would’ve been an LDR issue but it seems like the two boosts buttons might not even be impacting the same LDR?

Any pointers on what the cause might be?

Hi PA and welcome to the community!

Dave will need to help you with this, or he might suggest getting it repaired. I will flag this with him.

Cool. Anything else I should do at this point? Thanks for the help!

Hi there PA, can you let me know if your footswitch is connected while you are trying to activate the boost from the front panel? If it is, please try to assign the boost to a channel from the front panel and then activate the boost from the footswitch. We can troubleshoot further to get this working properly for you if this is not the issue. Thank you!

Thanks Terry. I don’t have the original footswitch, but after testing I haven’t been able to get any standard foot switches to work for switching channels or enabling the boost. Let me know what the best next step is.

Any other ideas to check Terry? Thanks!

I’m going to run this passed Dave to see if he can think of something we can try.

Thank You,

Hey PA,

What footswitch did you try? Your unit has a 6-pin din footswitch jack correct?

Thanks,

Terry

Hi PA,

After a deeper look, it seems you have the dual TRS footswitch jack model. It may just be a dirty jack. Deoxit can be your friend with jacks. Makes sure the amplifier is completely off, spray a TRS plug (or a 1/4" jack brush) and try to clean the contacts up. Let’s try that first.

Thanks,

Terry
