|Keeley Electronics took off, aided by a reputation for quality and customers such as Brad Paisley. Rebuilt versions of the Ibanez TS9 were used by Peter Frampton, Jon Herington and Ike Willis; Robert Keeley said he got his ideas for improving and tweaking existing effect pedals by reading commentary on various forums for guitar players. Since then, he develops his own pedals, starting with a boost pedal; his most popular effect is a compressor (first built in 2001), selling more than 27,000 copies.
According to Guitar World, Keeley Electronics has grown into “one of the world’s top sellers of guitar effects pedals”. Keeley claims that part of his success is due to carefully selecting electronic components with low tolerance.
