It depends how it stacks up against other boutique pres. Nobles are crazy expensive, Caveman too. Origin Effects are less expensive at around £550, as is the Jad Freer (IIRC), which, given the similar pedal board nature of the Walrus, I think is where it should be pitched. For my own use, £250-£300 is going to be my top end and there are plenty of offerings up to that figure for preamps that do what I need/want.
