I just received the Linden eq last week, as soon as I plugged it in it sounded really good. I have since ab'd it to the b15 in the hx stomp and find it (Linden) just gets me to a better sound more quickly.
Excited to get my particle accelerator soon.
Also, another preamp to check out are the Boss Organ tube pres, out of Boston. He repurposes old Leslie parts and builds some sweet sounded amps and pedals, here is my pre (not as big in person). I believe it is a 12ax7 for gain and 12au7 for the eq.
