Behringer Rehouse UV300

Took the plunge and ordered my first Behringer!
Its the UV-300 Vibrato, I'm advised is a fairly faithful clone of the old vintage Boss unit.
£18 delivered from Amazon

This rehouse took the best part of 5 hours so isnt the most straightforward. Ive seen it done other ways, but this way was mine.

I removed the touch switch so I could replace with a better quality push-SPST footswitch
The Ins/Outs got removed also and replaced with switchcraft style enclosed jacks.
The Power jack was removed; really you could just tack wires to this but for completeness...
Lastly, I removed the LED to replace with a white one.

I decided to keep the board mounted hardware otherwise (pots, switch) as I really wanted to keep the latching mode, and could NOT be arsed desoldering those 9mm pots between lots of SMD...
Therefore, I had to make some standoffs. These were 4mm bolts, and I enlarged the previous mounting holes on the PCB to accomodate.
The bolts were too long so had to be dremeled to size...

The only tough thing space wise to get this in a 125B was I had to move C18 = 1uF cap that is near the input jack to the "SMD" side of the PCB.
What I actually did was just cut it off and splice on a sub-mini cap from my own stock.

The pedals works and sounds lovely.
Here are some shots of the build. The final touch was to massacre the old box for the control panel, which I dremeled away then sanded down and super-glued to the case.
The case is white, and I sanded the top for a contrast (I got a few boxes which are slight blems on the top, but actually really like the effect!)

Drilled holes, slight oversize cos covered by the panel anyway :)

How it all was modded / made to fit! Inc standoffs...note C18!

Pretty neat internals in the end!

Added a DPDT under the PCB that parallels a 330nf cap with c15 (47nf) for extra slow sweep.
Cool mod!

awesome man, great job!

i reeeeaaallly miss my VB-2; i might have to take this project on in the near future. did you think about swapping the electrolytic caps for better quality? is there a lot of noise or hiss on the behr?

Hi

Its not really noisy at all
You can hear the sweep a bit if not playing but thats similar to most BBD based delay/chorus effects

The buffer is pretty decent. Not any real tone difference when placed in a bypass switch, its just a tad over unity is all. No biggie in a chain.

For £18 its a bargain imho
