Quilter Bass heads are driving bass tone to new heights (and depths!) Rather than your typical home brewed pre-amp slapped on to someone else's power module, Quilter heads use proprietary pro-audio power sections and our unique "tone mojo" to deliver superior dynamics. The Bass Block 800 is widely acclaimed for its "bottomless" power reserves for modern bass work, and the 200W Blocks offer warm "old school" tone with classic tube-type overdrive characteristics. Check out the InterBass for "plug and play" functionality for direct into PA, low power for acoustic gigs and headphone use as well!
