Members grrrunge Posted January 5, 2008 Members Share Posted January 5, 2008 So, lately i have found myself toying around with the stuff mentioned in my sig. However, 99% of the sounds i use with one of the two bands i'm in utilize the clean channel from my SP-77, the drive channel from my studio pre and the tube gain channel from my MP-1. That sort-of made me think: "hmm... if i could cram those three preamp channels into one box and save some rack space, it would be pretty nice, as i wouldn't have to tow around a 16U rack setup for smaller venues" So i have pretty much decided to try and build a preamp from scratch, with those three channels within (or three channels similar but superior to those - i need suggestions on those) by simply copying the circuitry from the three channels, and connect them with some sort of internal switching relay mechanism. The aim is a pre with warm cozy cleans that break at the right spot, a full blown warm roaring overdrive and a lead channel that makes the notes explode out of my speakers -no bulls, gadgets, loops, coffee cup holders or anything in this unit, just input, output and channel switching - end of story. what do you guys say? what channels would you stuff in it if you could choose freely between all the amp channels you ever tried ( schems please ) ? are there any other considerations i should do before jumping into this? I'd really appreciate all and any of your thought, so don't hesitate gimme' your two cents.. \ grrrunge Link to comment Share on other sites More sharing options...

Members separanets Posted January 5, 2008 Members Share Posted January 5, 2008 This may help. the premp is called "SLO-RECTO-JCM800" http://www.denn.ru/slo-recto/slo-recto-jcm800.jpg Link to comment Share on other sites More sharing options...

Members ocnor Posted January 5, 2008 Members Share Posted January 5, 2008 Trying to build such a preamp would be very difficult and time consuming. I think that you would be better off buying an Egnater or Randall RM4 preamp. Link to comment Share on other sites More sharing options...

I think that you would be better off buying an Egnater or Randall RM4 preamp. the time factor is not a problem, the difficulty neither (at least i'd like to think so). i considered the RM4 as well, but for now i'm looking for the fun/satisfaction in completing something guitar-rig related myself Link to comment Share on other sites More sharing options...
Members mohowski Posted January 6, 2008 Members Share Posted January 6, 2008 i've been playing with a very similar idea, combining the preamp of fender twin reverb and a JCM 800, and have been told that using relays in the signal chain for channel switching may cause popping noise when the relay swings. theres probably a wrong and right way to do it, but i haven't looked any deeper into it yet.

Members separanets Posted January 6, 2008 Members Share Posted January 6, 2008 The project name sounds promising, but the site says almost nothing about the circuit design have you tried it? Here's the English version of that guy's site: http://www.denn.ru/main_en.html Since he apparently spekas English you can contact to him. Here's his English version of the article you need: http://www.denn.ru/slo-recto/index_en.html However it's far from the original http://www.denn.ru/slo-recto/index.html So you can use a goole tranlation service like this: http://google.com/translate?u=http%3A%2F%2Fwww.denn.ru%2Fslo-recto%2Findex.html&langpair=ru%7Cen&hl=en&ie=UTF8 Link to comment Share on other sites More sharing options...
Members grrrunge Posted January 6, 2008 Author Members Share Posted January 6, 2008 The goal of this design was an Audi in the compact floor lamp guitar corpus following preampy: SLO-100 from SOLDANO, Dual Rectifier from Mesa / Boogie, Fender Twin Reverb from Fender and JCM-800 from Marshall, having thus creating enough universal tool guitar sound.

Members separanets Posted January 6, 2008 Members Share Posted January 6, 2008 following preampy, tembrobloki, on razvodke, about radiolampah, slightly provalennaya, podvodyaschimsya to conclusions, cherezvychayno important... how interesting, lol Do you understand anything?

Members RyGy Posted January 7, 2008 Members Share Posted January 7, 2008 for channel switching, and som eschematics you might want to have a look at www.londonpower.com He sells channel switching kits, circuit card kits, and his books have a lot of useful schematics. If you send him an email he will recomend which book you will find the most useful. He also sells some of the harder parts to find. I am in the process of building a standalone 10 watt two channel amp from his kits. I have a few days of work left. I am just wiring up the circuit boards, and transformers.
