I have 4 Kingsley tube preamp pedals for sale. These pedals are perfect putting into your effects loop return in your amp and have multiple flavors of preamps to feed into your power amp section. Avoid the 1 year wait for these hand-wired pedals. All preamp pedals include original power supply. No trades please. PM me if interested. Kingsley Maiden Blackface (BF): SOLD! Kingsley Constable Plexi: SOLD! Kingsley Squire Top Boost (TB): $425 paypal / shipped Kingsley Supro 1624T Custom: SOLD! This is a one of a kind / limited edition preamp pedal created by Simon Jarrett of Kingsley Amplifiers. Much like his Squire and Maiden tube preamp pedals, this is a similar type of preamp pedal, but based off a Supro 1624T preamp. All the components are hand-wired and it also uses a 12AX7 tube to get the warmth and dynamics of a very good tube amp. Just plug this into your effects loop return of your amp and hear this thing go from clean to scream. When you turn the gain knob past 12 o' clock, the tone starts getting thicker and overdriven just like an original Supro amp. The volume knob acts as a master volume, which is nice to have when you are overdriving the preamp. The tone knob helps adjusts how dark or bright of a tone you want depending how much gain you are using.
