The Schroeder Amplification "Dozer" amplifier was born out of necessity. At the time of its conception, I (Tim Schroeder) was playing in a band where I played bass, electric guitar and lap steel. My parts were looped live on all three instruments and most often heavily effected. The demands on the amplifier were great. The fidelity and dynamic range needed to be high and wide enough so that all of the loops and instruments could be heard clearly, and while being playing simultaneously. It also had to be powerful enough to keep up with the heavy hitting drummer and cutting guitar player.
Several renditions were tried before the Dozer was created. It’s smooth and effortless power combined with mindful construction and component selection allowed for clear and present production (and reproduction) of the complex tones generated by the effected instruments. It could also keep up with, if not drown out, the aforementioned bandmates.
Over the years, Dozer amplifiers have become the "go-to" live amplifier for bands like Wilco and Modest Mouse. They’ve also become a staple in recording studios as far away as Japan. It simply needs to be experienced to be believed!
Specs and features of note:
-Chassis made of 1/8" folded and welded aluminum, powder coated and screened.
-A 10 turn pot with locking dial is located just to the left of the tubes. This combined with the tip jacks (1 for each power tube) located on the back, make user bias and tube changes safe, fast and easy.
-All internal wiring connections made using silver or oxygen free copper wire of 99.9999% purity. Unlike generic "cloth covered" wire, it will not absorb airborne moisture, oxidize and/or degrade the signal over time. Using this wire requires special tools and means that EVERY wire needs to be cut to length and tinned with specially formulated silver bearing solder. A laborious and time consuming process but the resulting improvement to the sound is stunning!
-Custom power and output transformers that have all been developed over our decades long relationship with Mercury Magnetics. These transformers feature custom winds, lots of iron for reduced "sag", tight and transparent low end and silky highs.
