Product Description

The NEW Henriksen JazzAmp 312 is here. And it's fabulous! Here is a summary:

Upgrades You Can See:
  • Input Gain Control - One issue the JazzAmp always had is that while it works wonderfully with most humbuckers, it can be problematic with floating pickups or extremely hot pickups.  The addition of our input gain control provides the ability to adjust the input stage of the amplifier to the pickup's particular needs and gives the player optimum dynamic control.
  • Phantom powered combo 1/4"/XLR input jack - Traditionally the addition of this feature gives the player the option of using an instrument microphone as well as a standard pickup, or instruments with active on-board systems which use XLR cables and phantom power.  But we also see these as the future of analog instrument inputs because it allows for the use of our powered buffer cable (see below) which will be available as an accessory later this year. The phantom power is a full 48 volts.
  • 10kHz EQ Band Replaced by 7.2kHz - A common complaint about the JazzAmp was that the 10kHz control didn't seem to do anything, and frankly it didn't do very much that the average person could hear.  The 7.2kHz range is much more useful as a presence control and can really dial the tweeter in.
  • Reverb Upgrade - The reverb on the JazzAmp has always been a weak point of the design, so we have completely redesigned it using a totally different product. We are no longer using the Spin FV-1 chip, and have switched to the much improved Belton BTDR-2-S. There is no longer a need for an on/off switch, the reliability is much better and the sound is fantastic.  The Belton part can also be easily replaced with a longer tail version if so desired.
  • Headphone Jack - Not just a headphone jack, but it will also defeat the internal speaker when using a dummy plug so people can use an external cabinet with or without the main JazzAmp speaker.
  • Studio Grade Line Out - Another weak point in the JazzAmp design was the line out, which was really just a high impedance preamp tap.  The new Line Out is a studio-quality design that puts out an exceptionally high quality, low noise, low-impedance balanced signal. It is post-EQ and post-reverb.
Upgrades You Cannot See (the nerdy stuff):
  • Improved Power - The new JazzAmp has an increased clean headroom of around 12%, and operates much more efficiently which greatly improves the tonal quality and responsiveness of the amps.
  • Circuit Board Improvements - The circuit boards used in the JazzAmp have been significantly upgraded to include dual-sided ground planes, 3x larger traces, a new grounding scheme and improved AC filtering placement.  What does all that mean?  Lowest possible operating noise, greater reliability, and easier serviceability.
  • Custom Designed Crossover - we have on-boarded the crossover for the tweeter using a custom wound toroidal inductor to reduce unwanted noise and to optimize the tweeter for use with our designs.
  • Component Upgrades - We have upgraded several key components to improve sound quality in the preamp and power amp.
