I knew Tim DeWhalley who made these kits, and fitted them to his own build guitars and basses. He lived in the flat below me in South Croydon at the time. The electronics are good. I had a kit fitted to a 1962 Gibson SG. Fantastic sounds. If anyone knows where he is now I would love to contact him again. I know his brother, Chas was once a music critic for NME.
