Product Info
* Prices may vary. Check retailer for current pricing and availability.
The A-101-1 is a fantastic entry point into classic Steiner filter territory. Those vactrols really impart a creamy, organic character that's hard to replicate – it’s a go-to for ambient, experimental, and vintage synth sounds. Perfect for modular explorers wanting a core filter voice without a huge investment.
