$29.99 Amp! Webcor reel to reel amplifier. Purchased for $25
$29.99 Amp! Now officially a guitar amplifier, after adding a freakishly powerful 140 Watt Technics Speaker (purchased for $4.99 at thrift store). Amp produces about 10 watts. I use my “JamPlug” as a preamp, as this amp needs larger signal than pickups produce. If you count the JamPlug, the amp cost about $80. I can turn the guitar signal all the way up, JamPlug signal down, and get a beautiful overdriven distortion…classic tube sound!
