Hi,
After a two year break due to breaking my hand, I'm back to start playing again. As I'd previously sold all my gear, I thought I'd get another BTB as my last 770PB Amber was awesome (wish I'd never sold it now!). I picked up an 550MP-NTF in near mint condition with a slight issue on the dual cut pot for a good price. Sounded like a potentiometer easy fix swop.
However, after replacing said pot (model 3VR1VM304) the problem still remains. Adjusting this pot results in pops, dead sound and feedback. Therefore, I'm thinking I need to replace the preamp. However, looking online, this is no longer available in the uk. I believe you can get a set from Germany for 155 euros but i'd rather not if i could help it!
Has anyone had this problem before I'm wondering?
Would anyone have a contact / who is a guru who might be able to supply a circuit diagram/ know a supplier to use / or could be of help?
Many thanks in Advance - Mick.
