Custom shop

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

OMNIA:ARTS designs, builds, and modifies guitar amplifiers and audio equipment.  From passive, active, and digital studio monitor controllers using the latest 24bit 192k DAC's, to three channel guitar amps capable of clean warm tone as well as extremely hi gain, to tube and vca compressors, or hi-end stereo amplifiers.

More than a few omnia:arts (formerly omnia audio) custom pieces can be found in studios, homes, clubs, and colleges across the US.  Very soon another MX-72NV Neve inspired 10 channel summing mixer will be in a new home studio warming up mixes for another producer/engineer.

 Some examples of OMNIA:ARTS recent modifications include adding a hi gain distortion circuit to a guitar amp, adding more functionality to a mastering insert switcher, a DI to a mic preamp, a compression channel in a mixer, a bright switch in an amplifier, and led metering to a stereo amp. 

In the gallery below is various gear and projects built and/or modified by omnia:arts.  Some was built for the omnia:arts studio, while others were built for customers, 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 build 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.  

 

Along with residential, omnia:arts has installed audio systems in restaurants, clubs, factories, recording studios, and offices.  Take your home or business to where you need it.

Lab Series L5+ type guitar amp

Lab Series L5+ type guitar amp

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.

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 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.
