So my early reissue 1987x has been playing up a little recently - dropped it to the tech for once over and PAT test. He said it was ok, but changed the master volume pot (he thinks added on the back by the factory as it`s really well done - did the factory offer this?) - and he`s revalved it all the way through.
Wow- what a difference! On the normal channel it is so much fuller and louder - like properly plexi loud again. Sounds ace.
I`d been eying a Tonemaster twin, but may be unnecessary now.
