dustyh Posted November 4, 2006 Share Posted November 4, 2006 I have a Hammond JR20 tone cabinet that I can either turn into a liquor cabinet or a guitar amp. I was hoping that someone could direct me as to what I would have to do to modify the input so I could use it for something besides a bar. Thanks.

mate stubb Posted November 4, 2006 Share Posted November 4, 2006 You could buy a new guitar amp cheaper than you could modify that thing. It's only 20 watts. Liquor up! Moe --- Link to comment Share on other sites More sharing options...

Hammodel AV Posted November 6, 2006 Share Posted November 6, 2006 any Hammond tone cabinet is expecting a much-hotter-than-normal input (2 volt P-P approx.) and also a balanced (push-pull circuit, not just XLR type) signal. It is not suited for much other than a console Hammond (A/B/C/RT series). Hammond T-582A, Casio WK6600, Behringer D Link to comment Share on other sites More sharing options...
Hammodel AV Posted November 6, 2006 Share Posted November 6, 2006 Could also put it up on Craigslist in your area and see if a Hammond organ guy/girl might want it. Hammond T-582A, Casio WK6600, Behringer D Link to comment Share on other sites More sharing options...
Dave Horne Posted November 6, 2006 Share Posted November 6, 2006 I owned, what I thought was called, a PR20 (or PR40?) Hammond tone cabinet. I believe it contained two 12" and two 15" speakers. There was also a spring reverb. I'm not familiar with the JR20. No guitarists were harmed during the making of this message. In general, harmonic complexity is inversely proportional to the ratio between chording and non-chording instruments. Link to comment Share on other sites More sharing options...
Jim Alfredson Posted November 7, 2006 Share Posted November 7, 2006 The PR40 is a nice cabinet. On our last record I used one in conjuction with a 122 and it really helped get a nice, full, rich bass sound to tape. The JR20, however, is not as good. It has half the wattage and I believe a series of 10" speakers. The bass isn't as thumping as the PR40's twin 15" woofers and the amp is underpowered. I would turn it into a liquor cabinet or something cool. Keep it greazy! B3tles - Soul Jazz THEO - Prog Rock Link to comment Share on other sites More sharing options...
Steve Nathan Posted November 7, 2006 Share Posted November 7, 2006 I have a Pr-20 that is just furniture. I also had a PR-40 which I gave to a good friend who uses it just like B3-er describes. It is really nice for getting a rich deep bass tone. Don't rush me. I'm playing as slowly as I can! http://www.stevenathanmusic.com/stevenathanmusic.com/HOME.html https://apple.co/2EGpYXK Link to comment Share on other sites More sharing options...
