John East Uni Pre 4 knob - *READ DESCRIPTION* - partly working - *SOLD* £50 Edinburgh

[funkle]

Hi all

 

I list this as it needs some repair work, and I don't have the time to be able to do it.

 

This is the well known John East Uni Pre, 4 knob version. I bought it on here second-hand but only recently used it, and it seems to have some issues.

 

Volume, bass/treble, and passive tone all work fine. Active-passive switch fine. The system sounds good, and you can tweak the bass EQ and treble shelf easily using the internal thumb wheels. That's the good part.

 

The mid pots work, but it sounds more like a Wal-style filter EQ in use. This is not how it's meant to sound, and I ended up simply disabling the whole mid module by setting the jumpers appropriately on the board. It probably needs a new mid module.

 

Once everything was wired up, I found it was eating through batteries. That may have been my own cack-handedness in wiring up somewhere, or it may be there's a connection somewhere leading to it being 'always on'. I can't tell, and I don't have time to spend troubleshooting it, so I simply removed it.    

 

These are £235 new and working, so I have heavily discounted it to allow for the time/part costs it needs for troubleshooting. 

 

£50 posted in the UK.

 

Pete
