CUSTOM WORKS : Exclusive amps for exclusive guitarists
Semper Fi Studio has been making custom amplifierss for many years now and have tried to present a standard line of amplifiers. It turns out most guitarists have very different needs and wishes and all of our amps so far have reflected that. So instead of focusing on a single line of standard products, we offer semi-custom amplifiers and combos where the customer helps us in the final design and features of the amplifier.

Our amps are made using the best components available. We will make no claim that it is for mojo tone, but simply because our amplifiers are built to last a lifetime.

We are not very interested in making clones of other brands, that's what we have ebay for, but rather try to make unique and different amplifiers. There are many great tubes available that are not used by other brands.
- How about the classic directly heated triode 2A3, one of the first audio power tubes ever made - and still in production.
- Or what about an OTL with switchable twin output stages? One driven by a single 6L6 tube and the other by 3 tubes to get a mix of clean and crunchy tones on one or separate speakers!

THE SLAMP

A little devil in disguise...

The SLAMP is an amplifier that is compact and light weight enough to bring in your backpack. The SLAMP is made to be basic, fun and easy to use. It is made of the highest quality parts available. The single output tube is run in pure class-A and produces a thick comfortable overdriven tone. When overdriven to the maximum, the power of 10 watts is suprisingly loud.
The SLAMP is perfect for rock club venues, rehearsals, mic'd up concerts and occational jammings..

Power: 10watts, into 8 or 16ohm speakers
Tubes: One 12AX7 and one 6922 Power tube: One 5881 or 6L6GC

(We used it on guitars, synths, rhodes and run the saxophone through it, with Spiff Kiddo in studio)



THE OTL V COMBO
Mojo tone for the road...

A custom version of the the 30 watt OTL as a V8 combo with 2 x 12" Jensen speakers in upright placement. All in a smooth glossy sea green finish.

THE MINI V8 Prototype
