Title: convert se84b to guitar amp
Post by chris on 04/05/13 at 16:50:31

I have a Decware Se84B amplifier. Is it possible to convert this to a guitar amp?

Thanks,
Chris

Good question. I have a se84c or my se34 I would like do this to. Be nice if Mr D could give us info on this.

I doubt this is a cost effective project given the amount of work needed to convert versus the sale value of the amp before mod. I have been in the market for awhile for a low watt tube guitar amp so I naturally wish I could easily use one of my Decware amps.

Not sure what you qualify as a "low watt" guitar amp. For not much money I've had darned good combo amp sound from a Blackheart "Little Giant," and a vintage Fender "Musicmaster" bass amp (works great with guitar). The "Little Giant" used to be really cheap when first announced; the Fender is from the 'seventies and sometimes can be found reasonably cheap--I paid a bit more for a totally refurbished one with a great speaker and it's now my "go to" amp in my new home.

Low watts for my use is single digits. Thanks for the review. Music store in my neighborhood has a Blackheart Little Giant 1x12. I think I am on my way for a road trip this a.m.

They also have a 6 watt VHT head I will check out too. Hand wired, easy modding.

I'm currently involved in the thought stage of something like this. Having played guitar many years ago, I had tried a guitar in a normal stereo amp a few times and never had any luck. It worked, but just didn't sound right. I never knew why. Now, about 40 years later when I'm looking at a RIAA filter design for a phono cartridge, it dawns on me why that never worked. You need a phono level input without the massive equalization that a phono cartridge requires...in other words a pure flat gain stage of about 40 db. Such a design would be child's play compared to an RIAA phono stage design, but nobody offers a "guitar/mic" input that I'm aware of. You would also have to figure out how to handle the stereo/mono. So I'm curious as to how much interest this thread sparks.

Maybe the Zkit could be revamped for guitar use?

Title: se34 and ERR for acoustic guitar
Post by Matthew (was ML) on 07/04/24 at 15:29:06

I have been thinking about using my SE34i.4 with my ERR speakers as an acoustic guitar rig in the house, of course. Alternatively, I can put my Raven II Blender Guitar Preamp in front of it from the FX out (pre-master vol) or post-master volume of the Raven. Do you guys think that could work? I know little about input/output voltage, impedance, or other things electrical.
