Sansamp

"In 1989, after ten years exhaustive research and development with world-class guitar amplifiers, a tired but victorious B. Andrew Barta launched his unique SansAmp. This revolutionary pedal-sized tube amplifier emulator enables musicians to dial in monster tones and patch them directly to a studio mixer or stage PA. Its discrete 100% analog circuitry uses a hyper-realistic tone structure that includes mic and speaker simulation with pre and power amp distortion characteristics. Finally, it was possible to get stunning, consistent tones without brutalizing amps, heaving speaker cabs or futzing with microphones to find that elusive ‘sweet spot.’ Instead, the SansAmp delivered all of its mammoth sounds from a pocket-sized pedal."

"Savage Audio, Inc. began building high-end guitar amplifiers in 1994. Our very first amplifier was built for musician Beck and was used on the Grammy Awards broadcast the same week. We have been in continual production since.  All Savage amplifiers are handmade.

Savage Amplifiers are made in Savage, Minnesota, USA.  In addition to amplifier production, Savage is the largest service center for amplification in the Midwestern sector of the United States.

Date of production can be found on the tube chart inside the cabinet as well as on the chassis ." [Source: Wally Marx Jr, Savage Audio, email 10/12/2008]

Dating Scumback speakers

They now have labels with the manufacture date, but this only happened earlier this year. Before then approximate dates can be given based on label type/color/etc.

White sticker on frame edge on earlier models, sticker (currently) on the frame spoke with the model #, wattage, ohm rating and manufacture date. I also put a label on the back (last two years) that notes the model, ohm, power, magnet type, bass response (75 or 55). [Source: Jim Seavall, Scumback Speakers and Cabinets, email 26/5/2010]

Simple Amps

Joel Jones is the designer and builder of Simple Amps.

"We began Serialized production runs in 2009.

Everything currently in the market was manufactured in Laguna Niguel, CA. I moved operations to Franklin, TN in the Fall of 2009 and went through a financial partnership split in Dec of 09. Due to economic instability and a small over run on 2009 productions, a 2010 production run has yet to be made. Currently we will fill orders on demand.

Dating Simple Amps

Date of manufacture is serialized. On the Traveler Series a hand written serial numbers appears on the lower left baffle along with a matching number on the back of the chassis. Big Iron series use the same serialization but is label on the bottom of the chassis, typically under the power switch.

Format is XX###### - "XX" are the initials of the builder.

First ## is the year - 2009 would show up as 9, Second ## is month, and third set is unit number in production for that particular month.
i.e.
JJ90506 - JJ - was built by Joel Jones in May of 2009 and was the 6th unit of the month.

Only Initials used are JJ(Joel Jones) and SG (Sean Griffith) - employee provided by ex partner.

Any units that have no serialization or no screen printing are prototypes." [Source: Joel Jones, email 10/6/2010]
