Duncan Amplification

Some holy grail came in for a servicing! 1971 Marshall JTM45 MKII 50 watt (Model 1987).

Do you want AC/DC tones? Because that’s how you get AC/DC tones.

Quick little “repair” yesterday. The owner of this Crate V30 1x12 combo brought it my way saying it just stopped making sound one day.

Guitarists! If your combo amp suddenly cuts out (but still powers up just fine), check your speaker connection first. If that looks solid, try putting a cable into your effects loop, if you have one (plug one end into the send, the other into the return).

After those quick steps, check the tubes (even though they light up, they still might have an issue - try tube rolling, or systematically replacing one tube at a time with a known good one to see if anything improves).

Failing these quick troubleshooting steps, you may have a different issue.
