It's Not What We Sell, It's How We Sell.



The IsoGtr expands on our circuitry of the IsoDI by adding 3 additional transformer isolated instrument outputs to serve as an isolated signal splitter for sending your guitar or instrument signal to up to 4 amplifiers or effects chains (3 transformer isolated + 1 Buffered Main Output), our same ultra-clean wide bandwidth unity gain FET Buffered DI output (XLR), as well as an XLR Line input for Re-amping to any of the available instrument level outputs, all powered conveniently with an external DC power supply.

Housed in an extremely rugged 3.33″ x 5.25″ anodised aluminum extruded box (you know… the same type as our IsoDI that we ran over with a van to test under the most extreme tortures of the road). Built with high quality Neutrik TRS and XLR jacks, the IsoGtr will not only be a piece of gear you can trust to perform flawlessly on stage, but also a welcomed high quality part of your signal chain in any professional recording studio.
