August 14, 2019 · 7 sources

Electro-Harmonix announced two new pedals: the Bass9 Bass Machine, a polyphonic pedal that transforms a guitar into nine different basses, and the MOD 11, a compact digital modulation pedal offering eleven effect types. Both were available now at launch, with the Bass9 carrying a U.S. list price of $221.30 and the MOD 11 a U.S. street price of $151.0012.
Bass9 Bass Machine
The BASS9 Bass Machine transforms a guitar into nine different basses and requires no special pickups, MIDI or instrument modifications, as Premier Guitar reported in the maker's announcement1.
"The BASS9 Bass Machine transforms a guitar into nine different basses and requires no special pickups, MIDI or instrument modifications."
A rotary switch selects one of nine programs1:
| Program | What it is |
|---|---|
| PRECISION | Pays homage to the iconic Fender P Bass |
| LONGHORN | Longhorn bass |
| FRETLESS | Both electric and standup fretless basses |
| SYNTH | Synth bass |
| VIRTUAL | Virtual bass |
| BOWED | Bowed bass |
| SPLIT BASS | Split bass |
| 3:03 | 3:03 bass |
| FLIP-FLOP | Inspired by EHX's Octave Multiplexer, a '70s style logic driven sub-octave generator that tracks without glitches |
The pedal is equipped with independent Effect and Dry volume controls so guitarists can precisely tune their mix at the Effects output jack, plus an always-active Dry output jack that outputs the input signal at unity gain1. In the PRECISION program, the CTRL 1 knob controls the sub-octaves1.
The Bass9 comes equipped with a standard EHX 9.6DC200mA power supply1.
The Bass9 follows the company's earlier 9-series machines, the B9 Organ Machine and the KEY9 Electric Piano Machine45.
MOD 11 Modulator
The MOD 11 Modulator packs 11 different modulation effects that range from classic to exotic, plus advanced functionality, all in a compact pedal6. EHX described it in its own announcement:
"EHX introduces the Mod 11 with 11 modulation styles ranging from classic to exotic, all housed in a compact pedal."
The eleven modulation types include TREM (tremolo modulating the signal's volume), HARM (harmonic tremolo, splitting the signal into high and low frequency bands and modulating between the two), VIBR (vibrato modulating the instrument's pitch), UNI (paying homage to the classic Univibe, with Chorus and Vibrato modes plus added overdrive), CHORUS (a warbling, doubling chorus effect like the EHX Small Clone, with extra tri-chorus and bass chorus modes), ROTARY (a rotary speaker cabinet simulation with overdrive plus envelope control over rotation speed), FLANGE, TZF, PHASE, PITCH and FILT3. Each modulation type has two or three selectable modes that modify its behavior3.
Controls are kept simple3:
| Control | What it does |
|---|---|
| MODULATION TYPE | 11-position rotary switch selecting the active effect |
| RATE | Sets modulation speed; turning it to minimum enters Filter Matrix Mode in some mod types |
| DEPTH | Sets the depth or intensity |
| VOLUME/COLOR | Volume for the first six effects; other roles for the last five, such as feedback amount for FLANGE, TZF and PHASE |
| MODE button | Cycles through the modes of the active modulation type |
| Footswitch / TAP IN | Tap tempo via the built-in footswitch or an external momentary footswitch |
The MOD 11 is a digital pedal with buffered bypass, drawing 150mA, and comes with an EHX 9.6DC200mA power supply3.
Delicious Audio noted it is the third in a mini-series following the Canyon Delay and the Oceans 11 Reverb7.
