Jack's Guitarcheology is an Old Blood Noise Endeavors dealer.

From OBNE:

Expression Ramper allows you to pick two expression settings (A and B) and move between them, either in one motion or as a continuous LFO activated by a footswitch. The mini enclosure size takes up minimal space while creating new sounds out of any pedal with an expression input.

Controls include:

• Shape toggle to determine LFO motion (triangle, square, or one-shot)

• Alternate wave shapes accessible via Tap switch (smooth random, sharp random, or one-shot random)

• Assignable knob to set A position, B position, and LFO Rate

• Tap switch to set rate via tap tempo

• Footswitch to set expression output in motion, with momentary or latching operation

• Internal configuration for TRS, TRS reverse polarity, and TS configurations, as well as ability to replace built-in 50K digipot with 10K or 100K versions
