Hi Ian My first (and last 1964) ) tape echo box was made by Selmer. Always had to carry spare tapes as they wore out as I remember. Disaster if one broke during a performance, that would be my stage 'cred' down the chute.
. Like you I have always had an interested in echo units but could never justify the cost in later years. The Boss ME-70 was very good using dual effects but with that unit I could never quite get the sound I wanted. With the G1x I can get reasonable tones, but I dont seem to be able to match the Boss ME-70 echoes. Cant win'em all except by spending out more I guess.
I had a look at TVS3, looks too tempting . I'll just stick to what I have. I keep chasing different echo set ups but not finding exactly what I want. cheers John
