DP2 is a unique hybrid design including both vintage and modern circuits built around two
SP501 modules. The midrange crunch of the germanium sound of the mid 60’s, the low mid
punch and thick sound associated with British class-A from the early 70’s as well as the more
modern tone from the 80’s and 90’s.
The input stage is built around a high quality Swedish Lundahl transformer and a hi-gain input
stage followed by a selectable germanium circuit that adds more harmonics. Two different output
stages can be selected – either an electronically balanced stage, or a discrete Carnhill
transformer-balanced class-A stage. The vintage class-A mode produces a fat and punchy sound
with mid-range character and a warm top end, while the electronically balanced output stage is
less colored and perfect for clean amplification.
The major updates from the DP1mk3 to DP2 are a sweepable HPF from 30Hz to 400Hz which
allows precision crafting of the low end, and a separate switch to activate the instrument input.
The power supply has also been updated to for lower noise.
