Orange amps are quite sensitive for od-pedals. I use the Reeza on my Rockerverb just too push it a bit further, so low gain/ 10-11 o'clock on the Reeza. The Suhr does low gain stuff very well, but reacts also like an amp when you roll the vol.knob on the guitar back. As an alternative have a look at the Suhr Shiba Drive.
I'll try the Reeza at lower gain settings and see how much (if at all) the Splawn likes it. If not, I'll look into a Suhr Riot and Shiba Drive.
Thanks!
It takes always a bit of experimenting with od-pedals and amp. Gain on gain can choke the tone, so it's the art to find the sweet spots. Every amp reacts different. My Koch Multitone took every pedal, my Orange not. Had a Fulltone Distortion, did'n't work at all. It's important to get the bass on the amp and the toneknob on the Reeza matched.
