Thanks all for your comments, much appreciated. It seems to depend on the individual ear, I'm going a bit deaf these days maybe that's the problem.
Ok fitted the tonerider with a spare KiOgon (what does that name mean John?) loom that I had, I found it to be low on output, I had to up my amp gain and volume to get even a moderate sound from it.
The tone is fine, it has clear lows and highs but some of that may be down to John's tone pot. I'm no expert but I know what I like and POWWWEEERRR is one of them. Not that I use massive power but in my experience the more output there is, the better the sound.
Not a waste of money but I will be changing it, maybe a DP127 as recommended above.
