Past Brand Cabinet Users
Here are some famous players who were rumored to have historically used a similar type of cabinet in the past as reference and educational purposes for your tone quest or inspiration:
Joe Pass – Jazz Guitar Legend
Jim Hall – Jazz Guitar Legend
George Benson – Jazz Guitar Legend
This list should be taken with some skepticism as these players seem to be associated with all Polytone® amp and cab models with little photographic evidence to support these internet claims.
Speaker Photos of Polytone® Proprietary 15 inch and 8 inch Speakers for Guitar and Bass
1X15+2X8 Polytone® Proprietary 15 inch Speaker and two 8 inch Speakers for Guitar and Bass loaded in a 1970’s Pro Series™ 1X15 + 2X8 Guitar or Bass Amp Cabinet
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 large format, gently angled closed back cabinet is heavyweight, deadened with what looks to be fiberglass insulation, but the cab sounds pretty stark and revealing- dark at lower volumes and with a bit of a bite at louder volumes. This seems like Polytone® was attempting to make the Polytone® Model 101™ into a road worthy touring stack configuration in order to compete with the other amp manufacturers’ products hitting the big stages of the early to mid 1970’s.
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 up to mid 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.
Very little historical data exists on the web about these Pro Series cabinets. Please contact me if you have any more information that could be used to fill in the gaps.
