What was crackling in the circuit when it was in the bass?
Did the crackles happen when you adjust a pot? or when you move when playing the bass? or when you touch a pickup?
Or did it happen when it's laying on it's back on the floor and you pick a string?
I ask this, because it's far more likely that the problem is a pot, or a poor wiring connection than a faulty pre-amp. Physical problems are much more probable than an electrical problem.
I too have a Streamer Stage 1. If you're stuck, send your complete Pre-amp assembly to me and I'll take a look.
Yes, it's very probable the problem is the wires that have come loose.
Offer still stands - post it to me and I'll re-connect it and check it out in my streamer and check out any pots as needed as I can swap out bits with mine to find out exactly where any problem lies. I can do it over the weekend and back to you early next week, as long as we don't need new parts.
Hey Richard thanks very much for your very kind offer. I will have another crack at it over the next few days just to make sure it wasn't a loose wire.
Just to clarify, the noise is not linked to pots or input Jack or anything it seems. It would start randomly and stop randomly but slowly got less intermittent and more consistent hence why I felt it could be a component failure on the PCB itself.
Will report back once I've hooked it back up and tested it.
Thanks everyone for their help!
Btw, this Streamer with its Barts and this pre is simply one of the best sounding basses I've ever heard which is why I am keen to get it back up and running!
