I'm really considering forking out for one of these space echoes in the very near future. I can tolerate buffered pedals but I don't like losing my tone - in the past I have always quickly sold off pedals that I found sucked too much of my guitar signal; especially in the low end department. Some top end suck is tolerable - 'cause that's easy enough for me to rectify. So, before I jump into to buying one can anyone tell me if the Boss will suck anything out my guitar sound? Thanks.
