This attenuator gives you control of the speaker volume so you can get great cranked tone from your Epiphone Value Junior at studio or bedroom levels. It also includes a variable level, speaker-voiced line output so you can plug directly into a mixer for recording or live performance. Better yet, you can use the whole amp as a pre-amp into a bigger guitar amp.

The kit is easy to build and comes with instructions and all required parts including a pre-drilled and labeled faceplate. It requires no wiring modification to the amp and can be mounted conveniently on the back panel of the head or combo. You will need an extra speaker cable. If no speaker is plugged into the output jack, a power resistor is switched into the circuit so you can use it as a preamp only.

The mounting instructions are for an Epiphone Valve Junior Head or Combo. You can mount in the back or the front of the cabinet - see the pictures.

The BitMo 10-uator is rated at 10 watts. The kit now contains parts and instruction to allow configuration for 4, 8 and 16 ohm amps and speakers.

Note: The Studio 10-uator mods are compatible with the BitMo Spanky, Brat and Trio kits.

Recommend tube upgrades:
Standard: One JJ 12AX7 and one medium bias JJ EL84
Creamy Overdrive Distortion: One Tungsol 12AX7 and one low bias JJ EL84
Note: BitMo kits do not include tubes.

For an idea of how tube changes will affect the amp's sound check out this article at www.gearscore.com.

Warnings, etc:
These mods are very easy to do and reversible. This should NOT void the warranty and will work with any version of the Epiphone Valve Junior (head or combo) as well as the Blackheart BH5H head.
Tools you will need – screwdriver, soldering iron, solder, small allen wrench, wire stripper, needle nosed pliers.

Availability: Usually ships within 24 hours.
