dallas rangemaster!!

[Quencho092]

anyone tried one of these? the schematic is really really simple and available online for homebrewing. Clapton used it on the beano album, so did tons of other great 1960's guitarists. I hear it doubles the output every octave higher you go or something like that.

It seems like an easy project; especially if you get a kit like this: http://www.bigtonemusic.com/Rangerclone.html.

Re: dallas rangemaster!!

the raw mouser parts come out cheaper and this is way too easy to grab a kit. Good for really really big time beginners.

Re: dallas rangemaster!!

but, where can a nos oc44 be gotten?

Re: dallas rangemaster!!

i have been loking for an oc44, if you find one let me know

Hello Hello--
Yeah, a GOOD OC44 is hard to find. You don't need one to build a good sounding RM, though. I've built lots of RM and RM-type boosters using many different transistors and they all sound good. The key is biasing the tranny correctly for the circuit.

Re: dallas rangemaster!!

what exactly does a rangemaster do? I want to learn how to build/mod pedals, so im thinking about starting with this kit (itll be easier, and i have no idea what im doing). Also, what is the cost on the kit? I couldnt seem to find it onthe site, maybe im dumb or didnt look long enough, but what is it?

Re: dallas rangemaster!!

how do you bias the tranny??????

Orange Treble and bassbooster..
Plenty of good info out there.

Krank Amps makes one that is supposedly the same exact thing? I am not sure about NOS components though. http://www.krankamps.com/index3.html

Hello Hello--
First you have to make sure the transistor itself is good. This is a little tricky if you want to use an old germanium tranny like a OC 44 or any of the original ones from the 60's 'cuz most of them are noisey. Like I said earlier I've made RM-style boosters with lots of different trannys, and you can get a real good sounding one using a new silicon transistor. Biasing the tranny involves changing some of the values of the resistors in the circuit....different trannys may need different values in order to sound best. I don't know about any of the kits that are for sale......haven't had any experience with them.
A good treble booster should give you a solid gain boost as well as alot more upper-mids....Brian May [Queen] and Tonni Iommi [Sabbath] are good [but different] examples. They also sound best with British amps [Vox, Marshall, Laney, etc....] that are set for a good crunchy tone.
