I just come back to that one Paul mentioned: >> or you could go with a Line-6 one - http://line6.com/tcddk/ Because reading a little bit more about it I discovered the first SDK is U$D 180-ish but that additional 'blank' pedals are *ONLY 35 bucks* !! Thank you thank you line 6. I wish you could start a trend in manufacturers. Now, where is THB's filter code :) Marc.
