AMPLIFIERS FOR THE MOST DISCERNING BASSISTS
The 4 Stroke Series is our offering to the demanding modern bass player – everything you need, and nothing you don’t. Featuring all-analogue circuitry throughout, the 4 Stroke 300 & 500 speak with genuine authority, delivering powerful tones with a natural and rounded emphasis that leaves Class D amps in their wake. The Class AB 4 Stroke stays crystal clean and expressive all the way up, without ever becoming sterile or fatiguing.
The centrepiece of these amps is the uncompromising tone stack which allows for an unparalleled level of control over the EQ without the fussiness that plagues so many. The active four-band parametric EQ covers an enormous range and opens up limitless possibilities. Whether you need to sculpt your signature sound, bring out the character of your instrument or combat troublesome acoustic environments, the 4 Stroke deals with all comers in an instant. For the finishing touch, our proprietary Class A compression circuit tracks seamlessly, adding further punch and fatness. On the rear, you’ll find the usual essentials: two parallel speaker outputs (min. total load 4 Ohms), plus balanced and line level outputs. Available in 300W and 500W configurations, the 4 Stroke Series is the perfect tool for the contemporary bassist – powerful, usable, musical.
ALL ANALOGUE DESIGN
Trusting our ears and moving away from Class D technology altogether, the 4 Stroke is 100% analogue throughout. At the point of entry, the 4 Stroke features a new all-discrete Class A input buffer circuit. This contributes to crystal clear note definition and a highly detailed response, accurately reproducing even the most subtle nuances under your fingers. The Class AB output section (available in either 300 or 500 Watts) ensures these amps stay composed and assertive, whatever the venue. This design also means the 4 Stroke can also be used without a speaker load, perfect for direct recording in the studio.
ACTIVE FOUR-BAND PARAMETRIC EQ
Full control over the entire sound spectrum – not just the mids. Featuring four independent frequency controls, each with up to 18dB of cut or boost, the 4 Stroke’s Q curves have been engineered to achieve the perfect balance between precision and usability. The intuitive layout is typically Orange – “Do much more, with much less.” With no pre-defined contour or filter switches, the ability to fine tune your sound has never been more comprehensive.
Bass: 40 – 400Hz
Low Mid: 80 – 800Hz
High Mid: 250 – 2.5kHz
Treble: 550 – 5.5kHz
(Crossover between bands allows for even more cut/boost when required)
FOOTSWITCHABLE CLASS A COMPRESSION
Rather than a common hard limiter, the 4 Stroke’s Class A compressor design maintains the transients of the input signal for a dynamic playing response. The carefully developed sidechain has a fattening effect on the core tone at lower compression settings, whilst increasing the amount of compression adds a springy character to the attack, great for heavy thumb work. With just a simple level control (much like many classic studio units), the compression can also be engaged or defeated remotely with the optional FS-1 footswitch.
