My board right now has a Spark boost, a Fuzz Head, a KoT, a tuner and a Flashback delay mini. The Spark is a great pedal and I use it as a light OD and to gain up the first channel of my KoT but I've been using the Fuzz into the boost side of the KoT for that and I feel I could use a boost after the KoT. One that I could control the tone and add a little dirt too would be a bonus. Yes, I could just use the Spark but I'm thinking something else... Two different ideas: - Using a tremolo like the Supatrem or the Black Cat Mini Trem as boost/trem: I don't use trem that much but I could use some here and there. Both these pedals can do boost and add another speed/intensity to work as trem. The Supatrem seems to work best for this as you can have boost without trem. The Black Cat is smaller but you always have some trem going even with the speed all the way down. Not really a problem, I think. - Ditching the Flashback and adding a Strymon Deco: I use two different times on the Flashback: slapback and a little longer delay for lead work. Nothing too long, just a little longer than the slapback. The Deco can add dirt and seems to be able to control the high end and the low end with the secundary functions. The only downside is I would loose the Strum tempo function on the Flashback. Oh, it's a d@mn expensive pedal too! What do you say?
