  • $5 Stereo Preamp.

    Perhaps I should of posted this under General Gadgets instead of General Chat. Anywho, Last week I was fetching about for a preamp to use for adapting a reverb spring tank to my dual channel Leslie. I didn't want to dedicate a better quality pre for the job so I came up with this. OK, I'm cheap...but what can I say? I dug out an old cassette deck and put it in pause/record mode and it worked fine. I didn't like the big box though, so I cut it in half. I now have a utlity stereo preamp of a thousand uses. I'd been wanting to do this for some time. What's not to like. A pair of 1/4" jacks feeding VU meters,respectable preamps,rca line out and onboard power supply. Beat that Behringer. These things are like $5 at Goodwill but I know we all have one gathering dust.Click image for larger version

    Great concept !

    I have a couple laying around that I was going to donate. Now I have a good use for their guts.
    Thanks for the idea.
