Perfect for smaller gigs, the CTM 100 pairs the CTM 300 preamp with an all-tube, 100-watt power section. For home/ studio use, the CTM 15 offers 15 watts of stunning tube tone in an unbelievably compact head.

United Kingdom (January 17, 2012) – Ashdown is proud to announce two new lower-powered additions to the range for 2013. Perfect for smaller gigs, the CTM 100 pairs the CTM 300 preamp with an all-tube, 100-watt power section. For home/ studio use, the CTM 15 offers 15 watts of stunning tube tone in an unbelievably compact head. A reliable replacement for old technology, the CTM range delivers both huge amounts of tube tone and power.

The Classic Tube Magnifier 100:
Output power: 100 watts RMS into 2-, 4-, and 8-ohm cabinet outputs through speakon jacks, one for each ohmage, no selector to go wrong. Design frequency response: 30hz to 18khz at half-rated power.

Simplistic preamp with tube driven and recovered FX loop, dual gain stage with gain control, bass, middle and treble rotary controls. There are also handy, easy-to-f lick switches to further shape your sound in the form of a “Mellow” tone switch, “Bass shift” tone switch for deep/ clean bass, “Mid shift” which moves the frequency of the mid control for further shaping, and last but not least there is a “Bright switch” for enhanced definition at lower volume settings. All tone controls are pure passive and interactive.

A tube-driven DI out which is transformer derived with isolated ground means the stunning all-tube tone can be easily sent through to the PA on larger gigs.

User-settable bias for each individual power tube with calibrated, dual function VU meter on the front panel when in bias mode. The VU meter is also used to monitor output when in audio mode.

Each output tube is individually fused and user-replaceable, without removing the unit from its case (meter also indicates tube or fuse failure).

The CTM’s tube compliment is:
• Preamp
• Pre driver
• Main driver
• Output std
• 2 x Ecc83/12ax7 2 x Ecc82/12au7 1 x Ecc99 2 x 6550 (100W)

The unit is fitted with a cooling fan to change the air in the cabinet and supplement the large air vents, design temp < 55deg C inside case @ 25deg C ambient Extra large, overrated transformers and a heavy-duty chassis together with an 18mm plywood case make this a road ready beast, and at around 19kg it’s built to last.

The CTM-15:
Rated at 15 watts RMS using a very simple version of the CTM preamp paired with an all-tube power section, derived from the classic LB 30H. The CTM 15 is built using a heavy-duty, folded-steel chassis mounted to a rugged, caged housing, covered in a mildly textured paint finish for extra durability, styled with a punched Ashdown double-wing grille. The iconic Ashdown double wing logo and all important VU meter finish things off.

The CTM 15 surprises all with its tiny (H:140mm, 5.1”; W:235mm, 9”; D:155mm, 6.10”; 5Kg, 2.3lbs) but mighty appearance and its tone and power; sure to put a smile on the face of even the most discerning bass player. Despite its 15-watt rating, note these are Ashdown tube watts - don’t be fooled, the CTM 15 will out-gun many modern amps claiming to have far more power.

There’s way more than blues-rock fodder buried in the crevices of the most overused scale in music.



  • Explain how chords are generated from scales.
  • Create unusual harmonies, chord progressions, bass lines, and melodies using the blues scale.
  • Demonstrate how music theory and musical intuition can coalesce to create unique sounds from traditional materials.

Don't get me wrong, I'm all for blues music, but the blues scale can yield beguiling musical results that bear little resemblance to the traditional blues—particularly if one looks at (and listens to) the scale from a different point of view.
