The Double Trouble:

The Double Trouble is HarpGear's first mid sized amp which achieves 18W using a fixed bias class AB push pull 6V6 setup.  This amp is setup specifically for harmonica and uses all of our standard harp amp modifications we have become known for.  This amp was designed to add flexibility to our amp line and allow you to play in more medium sized venues with the confidence of knowing you won't need to mic the amp or connect the line out to the sound board.  The line out option is still standard for those who want to use it but the chances of you needing it are much less with the power this amp has.  The standard Double Trouble uses two Weber signature series speakers (ceramic x1 and alnico x 1) with one 12AY7 preamp tube and two 6V6 power tubes.  This amp uses a solid state rectifier but your ears wouldn't know it with the design we use.  We opted to go with the solid state rectifier because it allows us to keep the amp smaller without sacrificing any tone.   The tone control acts more like a high roll off allowing you to play with more highs when your session requires or allowing you to roll off the highs from the amp and get even more bass and distortion with less feedback.   This amp  has an oversized output transformer like the other amps and even more great bass to really accentuate those low notes while your playing.  The tube configuration for this amp is as follows:  (2) 6V6GT power tube (1) 12AY7 preamp tube.  This amp is 18"H X 14.5"W x 9"D and weighs 18lbs.  We went higher than wider on this one to make it easier to find room on stage and still give you a cabinet that is big enough to get great resonance.  This amp will generate 18 watts of power which comes across loud.  Players use this amp for small to medium gigs with great success with no assistance.  This amp can easily be used for large venues by connecting the line out to the PA and you will get the same great tone the amp is known for as loud as you or the soundman would like.  This allows you to use the amp as a monitor and the PA to get you heard over the rest of the band.  This amp is available in aged tweed only.   We no longer offer this amplifier in tolex.

All HarpGear Amplifiers include:

-Solid pine finger jointed cabinet.

-Solid 3/8" Baltic birch baffle for the best sound reproduction.  The baffle acts just like the sound board on a guitar and unlike particle board baffles which absorb the tone the Baltic birch reproduces your tone accurately.

-High quality custom transformers wound for us for a truly awesome sound as well as oversized transformers to add more honk to your amp and give you plenty of sweet round distortion.

-Mil Spec G10 Garrolite eyelet boards to prevent both tweed disease and moisture absorption common on pressed fiber boards which produces false capacitance and causes crackle and hum.  You will not have that problem with our boards and they will last a lifetime.

-Highest quality components including Sprague Atoms capacitors, Xicon Capacitors, Sprague Orange Drop or Mallory 150 tone caps, phenolic sockets, switchcraft jacks and custom transformers.

-All amplifiers are hand wired one at a time with the utmost attention to detail.  All component leads are straightened and cleaned before the are soldered to the G10 board.

-Values of components are increased in key areas to make the amplifier more responsive with all the bass and crunch a harp player needs. 

-Weber VST speakers and Jensen vintage speakers.

-An additional line out jack to run to the PA so you will never have a problem being heard over the rest of the band.  You can still use your amp as a monitor to hear yourself while plugged into the PA.  The line out can also be used to record directly into your computer line in or into a sound board.

Please feel free to contact me and discuss your playing style as there are options which can be customized to enhance your sound.  These amplifiers can be fitted with international power supplies also to allow overseas customers to use them also.  Please feel free to contact me with any questions you may have.
