Laney LX120RTwin Drive Channel Issues
« on: July 28, 2025, 06:33:15 pm »
Hello All!

A friend o'mine decided to drop this amp to the trash, but I volunteered as new owner!

Clean channel is working fine, but the Drive channel doesn't sound at all!

Preamp section is smd, I'm afraid this exceeds my current soldering capabilities, has anyone faced an issue like this, with this amp?

If it's too hard to solve, I might just turn it into a Guitar cab

here's Dougs 100, I would leave in the trash unless you've got scopes n sig-gens 100's of hours troubleshooting complex circuits


or just stab around, you might get lucky  :icon_biggrin:
