A cheap practice amp, gutted, then plugged into a 12 inch Jensen Speaker sounds excellent. I seriously feel a bit cheated paying $500 for a 'nicer' amp.
I got this idea from a YouTube video of a guy who wired this same amplifier into a Marshall Cab and was pretty impressed with the sound from that demo. I still had mine laying around so I did the same thing and plugged it into the 1x12 I'm making (Jensen Mod) and was even more impressed than I expected with the result. I went ahead and removed the amp portion from the original housing and slapped together my own housing with a speaker out jack.
Edit: I don't know why the photo keeps showing up sideways for me, i tried to rotate it and upload again but that hasn't fixed it. Apologies for this...
Nice build! Yeah. I have a Kustom KGA 10FX I won on ebay for 1 British penny! 😄 It's built in a way so that the amplifier can be taken out as stand alone and has a speaker cab output. I've been toying with the idea of doing something similar to this.
