I decided to do an experiment a few minutes ago, this involved connecting the pre-amp out socket on the front panel of the TKO 80 up to one of the line-inputs of the 300 Watt Behringer K3000FX Keyboard/PA amp, after plugging in my Squire P Bass, I first powered up the TKO 80 and then the K3000FX, no loud bangs or smoke occurred, so that was a good sign, with the bass, mid, and treble controls set to the 12 o clock position and turned up the pre and post-gain controls on the TKO 80, I was greeted by a nice loud and clean bass tone coming from the Behringer K3000FX when I plucked a string on the Squire P-Bass, so the idea of converting the TKO 80 into a bass preamp for use with the K3000FX is going to work perfectly.
The Squire P-Bass sounded nice and punchy through the setup, if I turned the volume up I found that I could easily get the glass panes of my loungeroom window to rattle, I had both the line input level, and master volume of the K3000FX set to the 12 o clock position and it sounded plenty loud enough to my ears with volume to spare.
Interestingly, the sounds I got were brighter than plugging the P Bass straight into the line input so I was correct in my thinking, the TKO 80's Bass, Mid, and Treble controls seem to give quite a useful range of tone from a deep Reggae style Bass, to a bright Rock Bass.
