Less feedback means more gain and more pronounced character. In Open mode there is no feedback at all, so the preamp runs at maximum gain and maximum tone. That makes the gain switch a tonal decision rather than only a level setting.\u003c\/p\u003e\n\u003ch3\u003eParts chosen for character, not for cost\u003c\/h3\u003e\n\u003cp\u003eAn EF86 handles the gain stage and a 6DJ8 drives the output. The signal path carries West-Cap, Vitamin Q and NYT paper-in-oil capacitors alongside 2-watt carbon composition resistors, with solid-core copper wiring throughout. Gain and bass cut are set on Grayhill rotary switches, so both channels can be matched exactly and a setting can be recalled for an overdub.\u003c\/p\u003e\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTwo channels of microphone preamplification with a DI section\u003c\/li\u003e\n\u003cli\u003eTransformer-balanced input and output\u003c\/li\u003e\n\u003cli\u003eFour feedback-controlled gain modes: Low, Medium, High, Open\u003c\/li\u003e\n\u003cli\u003eEF86 gain tube with a 6DJ8 output tube\u003c\/li\u003e\n\u003cli\u003eGrayhill rotary switches for gain and bass cut\u003c\/li\u003e\n\u003cli\u003eWest-Cap, Vitamin Q and NYT paper-in-oil capacitors\u003c\/li\u003e\n\u003cli\u003e2-watt carbon composition resistors and solid-core copper wiring\u003c\/li\u003e\n\u003cli\u003eHand-built with point-to-point wiring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: tube microphone preamp and DI\u003c\/li\u003e\n\u003cli\u003eChannels: 2\u003c\/li\u003e\n\u003cli\u003eBalancing: transformer coupled at input and output\u003c\/li\u003e\n\u003cli\u003eGain tube: EF86\u003c\/li\u003e\n\u003cli\u003eOutput tube: 6DJ8\u003c\/li\u003e\n\u003cli\u003eGain modes: Low, Medium, High, Open\u003c\/li\u003e\n\u003cli\u003eGain and bass cut control: Grayhill rotary switches\u003c\/li\u003e\n\u003cli\u003eSignal path capacitors: West-Cap, Vitamin Q, NYT paper in oil\u003c\/li\u003e\n\u003cli\u003eResistors: carbon composition, 2 W\u003c\/li\u003e\n\u003cli\u003eWiring: solid-core copper, point-to-point construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Highland Dynamics","offers":[{"title":"Default Title","offer_id":54555252523345,"sku":"60777","price":4229.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/HighlandDynamicsDualDelta4-71.jpg?v=1786971317"},{"product_id":"highland-dynamics-bg2-compressor","title":"Highland Dynamics BG2 Compressor","description":"\u003cdiv lang=\"en\"\u003e\n\u003cp\u003e\u003cstrong\u003eHighland Dynamics BG2 Compressor\u003c\/strong\u003e is an all-tube vari-mu compressor with a fully transformer-balanced signal path. The front end follows the British modifications of the Altec 436, while the output stage uses a pair of 6V6 tubes in the manner of the RCA BA6A and the Gates designs.\u003c\/p\u003e\n\u003ch3\u003eA vocal that no longer needs automation\u003c\/h3\u003e\n\u003cp\u003eA vari-mu circuit increases its reduction as level rises, so loud phrases are held down harder than quiet ones and the transitions stay smooth. Set correctly, a vocal track sits in the mix without drawing fader automation phrase by phrase. Two attack times are available, 30 ms and 110 ms, alongside six release times running from 270 ms to 2.8 seconds.\u003c\/p\u003e\n\u003ch3\u003eThree operating modes instead of three units\u003c\/h3\u003e\n\u003cp\u003eBritish mode delivers clean, smooth, high-fidelity compression. American mode passes more harmonic content and colours the signal noticeably. Line Amp mode disables compression entirely and leaves a driven tube amplifier, so the unit can be used purely for colour. The input switches between 600 and 150 ohms: the lower setting gives more gain and a stronger transformer contribution, enough to connect a microphone directly. A link switch pairs two units for stereo using ordinary instrument cables.\u003c\/p\u003e\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAll-tube vari-mu compressor with automatic levelling\u003c\/li\u003e\n\u003cli\u003eFully transformer-balanced signal path\u003c\/li\u003e\n\u003cli\u003eFront end in the style of a British-modified Altec 436\u003c\/li\u003e\n\u003cli\u003eOutput stage built on a pair of 6V6 tubes\u003c\/li\u003e\n\u003cli\u003eBritish, American and Line Amp modes\u003c\/li\u003e\n\u003cli\u003eSwitchable 600 or 150 ohm input impedance\u003c\/li\u003e\n\u003cli\u003eStereo linking with a standard instrument cable\u003c\/li\u003e\n\u003cli\u003eCustom oversized transformers and a Simpson meter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: all-tube vari-mu compressor\u003c\/li\u003e\n\u003cli\u003eBalancing: transformer coupled at input and output\u003c\/li\u003e\n\u003cli\u003eOutput stage: two 6V6 tubes\u003c\/li\u003e\n\u003cli\u003eAttack time: 30 ms (Fast) or 110 ms (Slow)\u003c\/li\u003e\n\u003cli\u003eRelease times: 270 ms, 400 ms, 700 ms, 1 s, 1.7 s, 2.8 s\u003c\/li\u003e\n\u003cli\u003eInput impedance: 600 ohm or 150 ohm, switchable\u003c\/li\u003e\n\u003cli\u003eModes: British, American, Line Amp\u003c\/li\u003e\n\u003cli\u003eFeedback: switchable settings\u003c\/li\u003e\n\u003cli\u003eStereo link: link switch, instrument cable\u003c\/li\u003e\n\u003cli\u003eMetering: US-made Simpson meter\u003c\/li\u003e\n\u003cli\u003eComponents: custom transformers, US and European capacitors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Highland Dynamics","offers":[{"title":"Default Title","offer_id":54555252621649,"sku":"28174","price":4229.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/HighlandDynamicsBG2Compressor1.jpg?v=1786971305"}],"url":"https:\/\/wrdtunes.com\/collections\/highland-dynamics.oembed","provider":"Wired Tunes","version":"1.0","type":"link"}
