Zakiya Hooker’s ‘One Scotch One Bourbon One Beer’ randtfilms

Fresh from the San Francisco Blues Festival 2008 featuring my friend and beautiful songstress Zakiya Hooker, killer Ron Thompson and smooth organist Deacon Jones, who said so cleverly at this annual lunchtime getdown “I’d like to send a shout out to my probation officer out there…and if you haven’t pawned your organ or bass at least once then you can’t play the blues, to which Ron replied “I don’t play bass!” A tribute to the late great John Lee Hooker.

where to buy? www.moiz.no Experience HEAD ONE Continuing with our line of fine amplifiers in Experience series, Experience Head One tube stereo headphone amplifier has been released on audio scene recently. Following basic design principle in accordance with philosophy of whole Experience series, this product offering an extended functionality unusual with amplifiers of the same type. beside it’s general purpose to drive different types of dynamic headphones, this device is designed with some additional and very useful features. Owners of transistored audio systems were kept in mind during design phase, and especially those who are interested to experiment with tube sound. So there is possibility go use this device as preamp with separate line output and an active subwoofer output. Should be mentioned that subwoofer output has similar bandwidth as line output but lower performance, so it’s usage is limited to lower frequencies. SAFETY Maximal safety level has been achieved by using output transformer where headphones and other outputs are connected to separate galvanically insulated secondary windings, even global feedback is accomplished on the same way. PRINCIPLE: Also, as difference from usual OTL solutions, perfect matching of impedances for different types of headphones is achieved using different taps on output transformer secondary winding, providing lossless sound quality on all outputs as the most important point with our amplifiers. As consequence of this …

LEARN MORE: bit.ly A Designs Audio JM-3001 Mic Pre/EQ Microphone preamp with EQ and instrument input Equally ideal for both studio recording and live sound use, the A Designs JM-3001 is a versatile preamplifier, equalizer and instrument input housed in a single-rack-space frame. Hand-built in the US, the new A-Designs device features three inputs — microphone, instrument and EQ/insert — which may be used together or independently. The product is also equipped with a highly musical three-band parametric EQ and high/low filters, as well as two independent transformer balanced outputs (microphone and EQ). The heart of the JM-3001 is its C12X discrete transistor operational amplifier designed by Carl Johnson that operates on ±30 VDC rails. The C12X is a high-gain, fast-slew, stable audio block with virtually no DC offset over the audio spectrum and is capable of driving a 50 ohm load at 50 Hz with very little current draw. It is used in the microphone preamp, instrument input amp and main output/EQ output stages of the product. The JM-3001’s microphone preamplifier is a single-stage, transformer-coupled and balanced I/O design benefitting from the C12X for ultra-transparent audio. This section feeds the EQ and preamp output mult simultaneously and includes phase reverse, a -20 dB pad, +48V phantom power with LED indicator and a plastic conductive gain control pot. The instrument input preamplifier is a single-stage, single-ended, high impedance input designed primarily with …
