Better still, the fact that the mic inside the cab is separated from the outside sonic influence also means that there is less interference with other instruments inside the band, resulting in a much cleaner and more easily manageable soundstage.

We developed the original, first generation “ISO BOX” years ago for one of the most famous Czech rock band’s live tour performance with the Prague Symphonic Orchestra (“FOK & Lucie Classically”), and it did the job with flying colors. This second gen, which currently drives the stage at the most acclaimed Czech music theater (Karlin Music Theatre in Prague), adds many important enhancements, most notably separability of both main parts, and vastly redesigned innards to provide the best guitar sound available for amplification and recording. Needless to say, we have also improved its appearance, transportability and overall usability.

At present, when split apart, the speaker-containing portion looks and acts as an ordinary 1×12″ guitar enclosure, so feel free to use it this way as long as you want. Then, if need be, join the parts together again in seconds to silence the beast. This added value makes the investment in this multi-purpose enclosure even more convenient.

The box is made from first grade birch plywood and sports the CELESTION Vintage’30 speaker connected to a high-quality input jack plate. The output is then realised via the pre-wired female XLR – type cable connector, ready for the mic insert, soldered to the male-XLR equipped output plate. The built-in long and sturdy mic gooseneck, together with both parts’ removable backs, allows you to easily arrange the right position of the mic with regard to the speaker and/or even change the speaker itself . Both the main parts are then joined together by two heavy-duty butterfly locks for easy and quick operation, and the rubber sealing is used at joint to minimise the potential for sound bleeding. Last but not least, both parts are kitted with quality strap handles and dedicated rubber feet for easy handling and transport.

This special cabinet can be equipped with a different speaker and/or with more microphone holders upon request. Naturally, its appearance is also subject to customizing, as is the case with all current ESH cabs and amps now.
