Custom shop, vintage restoration, and repair

Custom built guitar amps and recording equipment. Design, modification, restoration, and repair.

omnia:arts designs, builds, repairs, and modifies recording gear, guitar amplifiers, and audio equipment.  Custom builds include mics, preamps, compressors,  monitor controllers, as well as three channel guitar amps capable of clean warm tone as well as extremely hi gain. 

 

Sometimes a simple modification can turn a good piece of equipment into something outstanding.  Often companies try to cut as many corners as possible and their component choice isn't ideal.  Most  of the time these things can be upgraded giving the user are far better quality product. 

More than a few omnia:arts (formerly omnia audio) custom pieces can be found in studios, homes, clubs, and colleges across the US.   A custom made 3 in 4 out passive monitor controller was just been sent out 5 weeks ago with the customer saying it was the missing link in their studio.

Susanna from All the Pretty Horses has been using

the omnia:arts Alembic FX-2 guitar amp and loving it.

omnia:arts also does vintage restoration and repair. From decades old Neve modules to modern Hartke bass amps we can quote an honest price, given the work that needs to be done or the components that need to be gathered.

In the gallery below is various gear and projects built and/or modified by omnia:arts.  Most were built for customers, while others were built for the omnia:arts studio, colleagues, and friends.  Some use PCB's designed by various engineers worldwide.  Others were designed by omnia:arts.  In some cases omnia:arts was asked to prototype and test another designers PCB and built the piece from scratch. 

Custom builds require attention to detail and parts are selected by both importance, effect, and expense.  All custom built equipment comes with a 5 year repair warranty. The same warranty applies to omnia:arts own line of amps and equipment.  Ask about our reduced price on first off, used, and prototype pieces.

Overview of the Dual Pultec EQ-P2A

EQ540-X

Along with an EA2503 output transformer there are two 2520 DOA's made by Sparkos Labs in the signal path. Sparkos Labs DOA's really shined through and made the eq come alive. Comparable to Scott Leibers infamous DOA's

ALEMBIC F-X2

A very popular DIY guitar amp the Alembic is the tube preamp section of the Fender dual showman and was used by many great guitarists. This uses a solid state 120 watt power section making it great for recording and live.

Alembic F-X2

Two channel Alembic type 120 watt guitar amplifier. Tube preamp front end with solid state amp.

L5+

This was made for the studio but after a friend heard it we built a few more. The pcb was designed by Aion Electronics. Aion Electronics sells pcb's of classic guitar pedals.

Lab L5+ and Alembic F-X2

Lab Series type L5+

The Lab Series amps are considered by many to be the most tube sounding solid state amps ever built. Lots of great guitarists swore by these amps. This adds an extra overdrive cirxuit to make it even more versatile.

l5

This is a remake of the Moog design Gibson Lab Series L5 with some modifications. Aion Electronics painstakingly reverse engineered the preamp section of the L5 to put it into a pedal format. After hearing the preamp we were impressed by Aion Electronics work, so we decided to add a compatible power amp and put it into a 2u rack. Wanting a little more variety we added an overdrive circuit very similar to the Big Muff Pi op amp circuit. Aion Electronics has a great history write up of the L5.
