Historical Info (Click Here)
Polytone® was founded over 40 years ago in California, USA, and was making amp combos that people used for accordion, keyboards, jazz guitar, electric bass, and upright bass.. Interestingly, the company was founded by a jazz accordion player of fame for that era.
The small closed back cabinet is lightweight, deadened with what looks to be fiberglass insulation, but the combo sounds pretty stark and revealing- dark at lower volumes and with a bit of a bite at louder volumes. The speaker design is way over-engineered for strictly guitar use, as it doesn’t bottom out or fart like most guitar speakers when you try to play bass guitar through them at gig volume. But the Polytone® also doesn’t sound like a blanket is over the speaker when playing guitar through it, unlike some prominent bass speakers sound when playing guitar through them.
Impulse responses made with this cab can really sound great with many different types of digital amp models using clean or light gain, even bass amp models. If you try to play black metal or djent with these impulse response (IR) files, you will probably be very disappointed in them just as you would be with the real cabinet.
