Hi there,
I have a problem in that when in operate mode the sound randomly drops to a very quiet and muffled tone. If I switch to bypass, sound is normal, and when I switch back to Operate Mode, the sound will also return to normal sometimes.
The problem occurs frequently, but seemingly randomly.
I have changed all three tubes thinking this may be the issue, but the problem remains. I’ve also checked integrity of all cables used and they are good.
The signal chain is just guitar > amp input > amp out > PS100 amp in > PS100 Speaker out > cab. Impedances are matched correctly.
Please can you advise if any idea what the problem could be and/or if you can recommend where I can get it serviced if required (in UK)?
Many thanks guys - it is a great product when I can get it to work!
