Yeah! It works
I exchanged the bridge pickup with the T500 style from Merlin and it works great. Great tone, very high output and now Sustainer works perfect, as I wish it should. So if anyone have similar problem, then it may be caused by the bridge pickup... The only small disadvantage is that I can't match the volume of the neck pickup with the volume of the pickup in the bridge position, although I have turned the trim pot all the way up, the neck pickup is still a little bit quieter, but I don't care
All the best for you all on Xmas and New Year!
OT: If you were interested in my music, then there is a chart on the Polish pro-rock site and my band Hipgnosis tune Mantra just hit the no.1:
By clicking on the Hipgnosis on the chart list you may go to the sub site with the full version of the Mantra track, also available for download. The solo at the end of the track is me playing the Greco-made for Roland G-303 guitar synthesizer controller with the Roland GR300 Guitar Synthesizer (as used by Metheny, Fripp, etc). If you like the tune then you can vote and help us to stay on the 1st position
