Rickresource Rickenbacker Forum

Hi, Bounce Back... Many people wondering about this (various internet-forums), and by looking at the schematic, many people concluded it must have been some marketing phrase. The power supply looks fully conventional. Perhaps the thing that every solid state guitar amplifier 'should' do ( use curren...

Alternative universe question. If Rickenbacker guitars did not exist: 1) would The Beatles have been as big as they were For grins, let's add this bit of trivia (which most readers of Rick-trivia-books will know already) and move the 'what-if' topic further upstream. This article (in Dutch) sums it...

Thanks Greg, this the missing piece of the puzzle, thanks for sharing this info! And all laws of nature are applicable again ;-) Sure interested in having a look at the schematic some day, not in a hurry, glad already this info came around. I'll PM you in a few months, thanks already. And interestin...

I had a 260 once and I don't remember a boost. Thanks for the info, it then agrees with the published schematics as well, but the book-remark becoming more & more mysterious ;-) (or incorrect ;-) ) FWIW, as it seems then, only the first/early versions of the 230, 250 had the 'passive boost', bu...

Yes, I still have my modified 2030 bass, though that was the first body I built for it and it's sitting somewhere in the basement.] Oops, I hadn't watched that 1st pic in full detail the first time, it'sssss a bass!! And as I understand it it's all 'original', but you made/modified/in-fact-replaced...

250 003.jpg I don't recall anything like that on my 250. It was pretty straightforward with tone and volume knobs and a 3-way pickup selector. Of all the Rickenbackers I've owned and sold off over the years, I probably miss that one the most. Some guitars just feel great in your hands, and that one...

Complete speculation here, but (regardless of whether it was actually put into production) "passive boost" might have been some kind of multi-tapped transformer affair, like the 3-position switch on my Epi Jack Casady bass: it changes the impedence seen by the amplifier's input stage. The...

Related to the 230 Hamburg and 250 El Dorado guitars, the Tony Bacon/Paul Day Rickenbacker-book mentions a 'passive boost' for these models. But the available schematics on the Rickenbacker-site don't reflect this; just straightforward passive Vol & Tone controls. While 'passive boost' sounds li...

Could unfortunately indeed only be seen during a certain timeslot. I figure there will be more screenings of this documentary someday somewhere... It was certainly worth while I'd say. Not beyond great (why was there a guy with a purple 360 without strings ?! 8) ), but I'm glad I watched. Bruno Ganz...

Today's the day! Will be having a look!


Curious already, in case people here have already watched it, ...

how's the balance between 'real informative stuff' + old footage,
and say celebrities just talking a bit about the brand and telling nothing new?

I’d like to see the film. Roger Rossmeisl created designs I can look at and play on for hours. I'd like to see it as well! In about 2 weeks there's an online opportunity (US$12): Available June 5, 2021 6:01 AM GMT+2 https://watch.eventive.org/newjerseyinternationalfilmfestival2021/play/6057a87901e4...

Thanks for the reply, interesting to hear. Hadn't seen like this before, but sure makes sense.
Trying to recall which combination of 'brands' and 'old speakers' I may have seen the most, possibly mostly Celestions, no idea if they have been using it.

OK nice, 'riddle' solved, thanks all!

FWIW, note that the TR25 schematic likely has a small drawing error in the tremolo-LFO section. (LowFreqOscillator) Unlike the 'more usual' phase shift oscillator (topology with 3 cascading RC-sections), Rickenbacker uses a Twin-T oscillator. As drawn in the TR25 schematic it won't work, the midpoin...
