Wampler is mostly known for distortion pedals and Ego compressor. But they have a couple of nice Delay / Reverb pedals that might interest Ambient guitarists.

• Doctor Lo-Fi Delay - born from a collaboration between Brian Wampler and superstar, tele-master Brad Paisley, The Doctor Lo-Fi Delay pedal exudes a gritty character that works as well for laying down an ambient sonic bed as it does for old-school slapback. Surely it’s a specific pedal due to its lo-fi self-oscillating repeats.
• Ethereal - Reverb and Delay. It is compact, easy to use and… Ethereal. 4 delay patterns. Plate style reverb.
• Faux Tape Echo v2 - Every aspect of the modulation that gives the Faux Tape Echo pedal a unique function and tone and makes it desirable for people who want their delay tone to sound as good as tape delay units but without all the maintenance, supplies, and hassle. Based on the hugely popular best seller of the previous models, the v2 offers the same purity of signal path, the same depth of tone on the repeats and most importantly, the addition of sub divisions at 1/4, 1/8, dotted 1/8 and triplet based on your tap tempo.
• Ego Compressor - I guess this is the most popular classic guitar compressor. That’s all that you should know about this pedal.
