Pedals that stack with the Biyang Pre-19 Preamp

Behringer Chorus Symphony

Put Behringer Chorus Symphony after Biyang Pre-19 Preamp in the signal chain, clear of Biyang Pre-19 Preamp's own gain stage

Catalinbread SFT

Catalinbread SFT leans warm right where the bright tone needs it

Rocktron Big Crush Compressor

Biyang Pre-19 Preamp's gritty character and Rocktron Big Crush Compressor's smooth voice sit in the same lane rather than fighting each other

One Control Lingonberry Overdrive

Run One Control Lingonberry Overdrive after it and the bright edge settles into something more warm

Line 6 DL4 Delay Modeler

Keep Biyang Pre-19 Preamp's gritty voice out front: Line 6 DL4 Delay Modeler goes after Biyang Pre-19 Preamp in the signal chain so its warm voice doesn't muddy it — goes in the amp's FX loop (or last, into a clean amp)

JAM Pedals Delay-Llama

JAM Pedals Delay-Llama's analog warmth voice goes after Biyang Pre-19 Preamp in the signal chain — it's not there to compete with Biyang Pre-19 Preamp's own gritty character — goes in the amp's FX loop (or last, into a clean amp)
