Hi all, I really like the sound of PF-500. If someone is deciding to buy one, go for it! True ampeg tone! Well I like tube tone also and my budget is tight, so I'm thinking to buy preamp, that would give some tube sound with my PF500 sound. I'm looking Summit Audio TD-100 My question is can I run signal from Summit DI to PF and then from PF to mix? Would that signal have tube tone + ampeg sound? Are there any other sugestions? I know that REDDI is the best but any ways... Thanks for your replys.
