Spring Reverb Unit Conversion Kit for Epiphone Valve Junior Amp
I was going to call it the Spaghetti Western Swamp Surfer ...
This kit contains all the parts and instructions necessary to CONVERT an Epiphone Valve Junior head into a stand-alone, 100% tube driven spring reverb unit. It includes a 3 spring Belton tank (Belton bought Accutronics), other quality parts and faceplate label as seen in the photo.
"I will now proceed to entangle the entire area."
OK… I now this may be confusing but I have 2 reverb kits for the Epiphone Valve Junior amp.
I have been building prototypes for the last 2 years, several from scratch. 2 configurations have finally made it through the BitMo sausage grinder to be released as kits.
My criteria for an acceptable BitMo product –
· Must sound great
· Must offer good value for the money
· Must be easy enough to be built by actual guitar players (maybe even drummers ;^) without too much hand-holding from me (I have a day job.)
The following table compares the 2 kits.
Spring Reverb Unit | B-verb |
Converts an EVJ head into a stand-alone reverb unit | Adds reverb to an EVJ head or combo |
Requires the Unit to be plugged into another amp | The EVJ still works as an amp with added reverb |
Tube driven spring reverb tank | Tube driven digital reverb emulation chip |
Must start with a stock amp (or close to stock) | Plays well with other BitMo mods (Tweaky, Trio, etc.) or most other popular mods |
Thunders when kicked | No thunder - just 'verb |
Sounds great | Sounds great |
This is the BitMo Spring Reverb Unit conversion kit, a stand-alone reverb unit like the classics from Fender. You need to plug the new output jack into another guitar amp, mixer or FX loop. The conversion uses the tubes to drive the spring reverb tank and to recover and mix the signals. The speaker output jacks are still functional but the speaker volume will be low and clean. The reverb signal is not mixed in the speaker output.
The BitMo Spring Reverb Unit provides classic wet “surf-alicous” reverb. Use your guitar knobs to control guitar tone and level (dwell). The output jack contains a unity gain guitar preamp signal and the reverb mix. The LEVEL controls the amount of reverb in the mix – from just a touch to too much ;^)
Sounds great! (IMHO)
(If you want to ADD reverb to your amp, please see the listings for the BitMo B-verb.)
Amp not included with the kit –
You must supply your own virgin, non-modded EVJ head.

Note: This was originally called the BitMo Reverb Jr. I decided to rename and re-label it to help differentiate it from the BitMo B-verb add-on kit. The demos still use the old name. Even more confused?
Tools you will need – drill and bits, screwdriver, soldering iron, solder, wire stripper, needle nosed pliers electrical tape.
I would classify this as medium difficulty - not recommended it as a first modding project. It takes 2-3 hours and does some restructures of the circuit. I assume no responsibility for the quality of your work.
I’m sure you will love this project! It has been in development for a long time.
I welcome questions and suggestions and appreciate your feedback.
Note to international buyers: I will ship anywhere in the world but I am not responsible for customs delays or non-delivery problems - especially to Italy!
Thanks for looking,
Bruce Hutcheon

It sounds exactly like I hoped it would: nice and warm with the reverb turned down, and full-on, Dick Dale-style reverb when it's turned up.
